    A Study of Salinity Characteristics and Spectral Characteristics of Salt-affected Soil in Caka-Gonghe Basin
    QI Hao-Ping, WENG Yong-Ling, ZHAO Fu-Yue, FANG Hong-Bin
    REMOTE SENSING FOR LAND & RESOURCES. 2010, 22 (s1): 4-8.   DOI: 10.6046/gtzyyg.2010.s1.02
    Abstract   HTML   PDF (888KB) ( 1359 )

    The salinity characteristics and spectral characteristics of salt-affected soil constitute the basic research

    contents in hyperspectral remote sensing quantitative monitoring of saline soil. The Caka-Gonghe basin is situated in the

    eastern margin of the Qaidam Basin, where the soil salinization is typical. Based on the physical and chemical analysis of

    the soil and laboratory spectra of the samples, this paper discusses the salinity characteristics and spectral

    characteristics of the samples and analyzes the regularity of the variation of the spectral characteristics with the

    salinity characteristics. Studies have shown that chloride saline soil is dominant in the study area, and that the spectral

    characteristics show marked differences due to the different salinities in the saline soil.

    Abstract   HTML   PDF (784KB) ( 1616 )

    Active structures as well as geological disasters and earthquakes frequently occur in Sanjiang region, and hence

    regional geological environment stability becomes the most important problem in the study area, which affects seriously

    many aspects of people’s life. To evaluate the stability of the study area quickly and effectively, this paper adopted

    remote sensing and GIS technologies to analyze the geological factors related to the stability. With the Weight Method of

    Evidence based on such regional geological environmental factors as earthquake, geological disaster, active fault,

    litohology and geomorphology, the authors made a quantitative assessment of the stability in Jinshajiang area of Yunnan

    province and divided geological environment stability areas. On such a basis, this study not only probed into the

    quantitative assessment technology and methods for regional geological environment assessment but also provided effective

    information base and decision support for resources development.

    Abstract   HTML   PDF (721KB) ( 1532 )

    In order to find out the desertification status of the Yangtze River Basin, this paper discusses the effective

    automatic sorting of desertification land type, and the method for overcoming the phenomena of different things with the

    same spectrum and the same thing with different spectra. Based on the waterpower desertification land, this paper probes

    into the extraction method for land cover information in western Hunan area by using TM data information of Landsat. In the

    light of multi-band data of TM, the normalized index(MNDWI NDVI NDBI) and the difference index were adopted. This paper has

    also put forward the suggestion of multi-layer information extraction strategy based on TM images of TM3, TM4 and TM5

    spectra. The results show that this method is simple and practical, and hence can serve as an effective way for remote

    sensing information extraction of ground object.

    MENG Kun, LI Ji-Na
    REMOTE SENSING FOR LAND & RESOURCES. 2010, 22 (s1): 26-29.   DOI: 10.6046/gtzyyg.2010.s1.07
    Abstract   HTML   PDF (710KB) ( 1063 )

     For level 2 remote sensing data of CBERS-02 satellite, polynomial model is usually used in geometric precision

    correction. Compared with polynomial model, rational function has higher precision in hilly or mountain areas. With the

    mountain area in northwest Gansu Province as an example, the authors compared and evaluated the results of two models

    applied to geometric precision correction. For an area with elevation over 4 000 m, the precision of rational function is

    2~3 times higher than that of polynomial model.

    The Design and Implementation of Qinghai-Tibet Plateau Environmental and Geological Integrated Appraisement System Based on RS Data
    HE Zheng-Min, YAN Yun-Peng, FENG Min, WANG Hong-Rui
    REMOTE SENSING FOR LAND & RESOURCES. 2010, 22 (s1): 30-34.   DOI: 10.6046/gtzyyg.2010.s1.08
    Abstract   HTML   PDF (902KB) ( 1085 )

     With Qinghai-Tibet Plateau as the study area, this zonal environmental and geological integrated appraisement

    system based on RS data is mainly composed of three kinds of integrated appraisement models, i.e., Overlay Computing,

    Analytic Hierarchy Process (AHP) and Fuzzy Gray Multi-method. There are three parts of components in this appraisement

    system, which are modal running platform, modal spatial system and modal attribute system. With this appraisement system,

    different models could be used to evaluate environmental and geological status of the same place, and the appraisement

    results from different models could be analyzed separately and compared with each other. In addition, the system solves the

    data conversion problem for different data types and the cartographic problem in the printing process of the appraisement

    result. With this appraisement system, the researchers needn’t to open both GIS (Geographic Information System) and RS

    (Remote Sensing) software at the same time to operate spatial data such as ArcGIS and ERDAS. With the adoption of Overlay

    Computing Method and Fuzzy Gray Multi-method, the appraisement system selected five kinds of indexes, namely Disaster,

    Hungriness, Marsh, Glacier and Fault, in the Qinghai-Tibet Plateau to evaluate local environmental and geological status.

    It is proved that the appraisement result is well consistent with the field survey data.

    A Tentative Discussion on the Continental Glacial Sheet in East Qinghai-Tibet Plateau
    ZHAO Fu-Yue
    REMOTE SENSING FOR LAND & RESOURCES. 2010, 22 (s1): 39-44.   DOI: 10.6046/gtzyyg.2010.s1.10
    Abstract   HTML   PDF (1115KB) ( 1459 )

    Qinghai-Tibet Plateau is a region with the largest area of glaciers in China and is called the water tower of

    Asia. The key characteristics of glaciers evolution in Qinghai-Tibet Plateau are their incessant area shrinkage, continuous

    thinning of their thickness and ceaseless reduction of their ice reserves. According to the results of remote sensing

    survey in Qinghai-Tibet Plateau, this paper deals with the features of the continental glacial sheet in east Qinghai-Tibet

    Plateau based on remote sensing images, such as its geological features, distribution areas, formation stages and formation

    environments. The effects of the geological setting on the formation of the continental glacial sheet in east Qinghai-Tibet

    Plateau are also tentatively discussed.

    Remote Sensing Survey of Existing Glaciers in Qinghai-Tibet Plateau
    ZHANG Rui-Jiang, FANG Hong-Bin, ZHAO Fu-Yue, ZENG Fu-Nian
    REMOTE SENSING FOR LAND & RESOURCES. 2010, 22 (s1): 45-48.   DOI: 10.6046/gtzyyg.2010.s1.11
    Abstract   HTML   PDF (639KB) ( 1974 )

    An investigation of existing glaciers in Qinghai-Tibet Plateau based on remote sensing technology has revealed

    the areas of existing glaciers in different ridges. The decreased area of existing glaciers in Qinghai-Tibet Plateau from

    the middle of the 1960’s nearly to the 2000’s was also found out. Different kinds of remote sensing data suitable for the

    investigation were chosen according to the characteristics of glaciers distribution. Terrain correction of the remote

    sensing data is necessary to reduce the influence of topography on the investigation precision. Much seasonal snow existent

    on the high mountains must be eliminated. It is difficult to eliminate seasonal snow in most areas because it is so similar

    to the existing glacier. Many ways are summarized to eliminate the seasonal snow. Till the year of 2000, the area of

    existing glacier in Qinghai-Tibet Plateau was 46 887.23 km2, suggesting a shrinkage of nearly 3 941.68 km2. About 131.4 km2

    of existing glaciers was reduced per year from the middle of 1960’s approximately to the 2000’s in Qinghai-Tibetan

    Plateau.

    The Evolution of Existing Glaciers in the Past 30 Years in Qinghai-Tibet Plateau
    ZHANG Rui-Jiang, FANG Hong-Bin, ZHAO Fu-Yue
    REMOTE SENSING FOR LAND & RESOURCES. 2010, 22 (s1): 49-53.   DOI: 10.6046/gtzyyg.2010.s1.12
    Abstract   HTML   PDF (1446KB) ( 1173 )

     Qinghai-Tibet Plateau is a region with the largest area of glaciers in China and is hence called the water tower

    of Asia. The glaciers supply lots of water source for the rivers in China and Southeast Asia. The key characteristics of

    glacier evolution in Qinghai-Tibet Plateau are their incessant area shrinkage, continuous thinning of their thickness and

    ceaseless reduction of their ice reserves. The evolution of glaciers varies at different stages and in different places.

    From the end of 1960’s to the end of 1980’s, the area of glaciers increased slightly due to the slight increase of

    glaciers. Since the end of 1980’s, the area of glaciers has shrunk sharply, and their decreasing speed is faster than ever

    before, especially in the districts around Tarim Basin and Himalaya Mountains. The area reduction of existing glaciers in

    Pamirs Plateau is the largest in Qinghai-Tibetan Plateau. The area reduction of existing glaciers in Himalaya and Qilian

    Mountains are also rather considerable. The area reduction of existing glaciers in Qiangtang Plateau and Kunlun Mountains

    are relatively small.

    Remote Sensing Survey of Existing Snowlines in the Past 30 Years in Qinghai-Tibet Plateau
    ZHANG Rui-Jiang, ZHAO Fu-Yue, FANG Hong-Bin, ZENG Fu-Nian
    REMOTE SENSING FOR LAND & RESOURCES. 2010, 22 (s1): 59-63.   DOI: 10.6046/gtzyyg.2010.s1.14
    Abstract   HTML   PDF (1594KB) ( 1318 )

     Based on the study and analysis of ETM images of glacier distribution in Qinghai-Tibet Plateau, this paper puts

    forward a new method for ascertaining the altitudes of existing snowlines. With this method, the altitudes of existing

    snowlines in different ridges of Qinghai-Tibet Plateau as well as the variations of existing snowlines from the middle of

    the 1960’s approximately to the 2000’s were detected. The investigation results show that the altitudes of existing

    snowlines in Qinghai-Tibet Plateau range between 4 000 m and 6 000 m. The snowlines ascend gradually from the east to the

    west of Qinghai-Tibet Plateau. There are three ways of the variation of existing snowlines in Qinghai-Tibet Plateau:

    rising, lowering and basic stableness, with the rising of the existing snowlines in Qinghai-Tibet Plateau being dominant.

    The change of existing snowlines is closely related to the evolution of existing glaciers.

    Eastward Migration of the Watershed of Inflow and Outflow Rives in the Mid-southern Qinghai-Tibet Plateau and the “Nagqu Movement”
    SUN Yan-Gui, ZHANG Kun, YU Jing-Hui, MA Shi-Bin
    REMOTE SENSING FOR LAND & RESOURCES. 2010, 22 (s1): 64-68.   DOI: 10.6046/gtzyyg.2010.s1.15
    Abstract   HTML   PDF (1123KB) ( 1187 )

    Making use of the remote sensing technique and field survey, the authors have studied the Quaternary geology of

    the Qinghai-Tibet Plateau since 2003, and the results indicate that the watershed of China’s inflow rivers and outflow

    rivers in the mid-southern Qinghai-Tibet Plateau was formed in early Holocene. The Nagqu Movement that occurred at the last

    stage of late Pleistocene was an important crust movement forming the dividing range. The remote sensing survey also

    discovered that the dividing range was situated in the Tangra Yumco area. The crust movement resulted in eastward migration

    of the watershed for 500 km, and the early riverhead area of the Nujiang River consisting of the Siling Co and Namo Co

    lakes became inland basins. Based on the results of the remote sensing survey of the Quaternary geology which mainly

    include the fossil river courses, the angular unconformity between Pleistocene and Holocene and the Nagqu movement in the

    mid-southern Qinghai-Tibet Plateau, this paper deals systematically with these phenomena and regularities.

    An Analysis of Characteristics and Driving Forces of Land Desertification in Sanjiangyuan Region
    LU Yun-Ge, LIU Xiao, ZHANG Zhen-De
    REMOTE SENSING FOR LAND & RESOURCES. 2010, 22 (s1): 72-76.   DOI: 10.6046/gtzyyg.2010.s1.17
    Abstract   HTML   PDF (1018KB) ( 1147 )

     Based on the MSS(1975), ETM+(2000) and CBERS-02b(2007) images, the authors conducted monitoring of land

    desertification in Sanjiangyuan region with the emphasis placed on the characteristics and driving force of land

    desertification variation. Desertification land is mainly distributed in the flat plateau, close to the river and roads.

    The area of desertification land increased obviously between 1975 and 2000, especially in the Yellow River headwaters area,

    because of the warming and drying as well as the disturbance of human activities such as panning and overgrazing. In

    addition to the increasing desertification area, the degrading level was aggravated and the changes in spatial distribution

    were frequent. After 2000, the Sanjiangyuan Reserve Area was set up with the purpose of reducing the impact of human

    activities as much as possible. On the other hand, the precipitation was increasing. Since then, land desertification in

    Sanjiangyuan region has tended to be improved.

    The Neotectonic Process Causing the Conversion of the Qinghai Lake from an Outflow Lake into an Interior Lake
    ZHANG Kun, SUN Yan-Gui, JU Sheng-Cheng, MA Shi-Bin, YU Jing-Hui
    REMOTE SENSING FOR LAND & RESOURCES. 2010, 22 (s1): 77-81.   DOI: 10.6046/gtzyyg.2010.s1.18
    Abstract   HTML   PDF (1066KB) ( 1472 )

     The assumption that the Qinghai Lake was once a drained lake and later became an interior lake due to the uplift

    of the Riyue Mountain has been widely accepted in the past. In this paper, the ancient fluvial facies and lacustrine facies

    were explored in its dimensional layout on the basis of some satellite data from ETM and ASTER. Statistical analysis of its

    sedimentary characteristics and chronostratigraphic studies indicate that the main stream of the Yellow River was the Buha

    River, which passed through the Qinghai Lake and connected the major stream course of the Yellow River in Guide Basin at

    0.10 Ma. Along with the uplift of the Riyue Mountain, the Qinghai Lake became an interior lake and shrank rapidly; at the

    same time, the Yellow River was forced to cut through Longyang Valley and continued its development in Gonghe Basin.

    Abstract   HTML   PDF (718KB) ( 1501 )

    In recent decades, with the remediation of Yangtze River and the control of bank collapse, the situation of

    rivers along the Yangtze River in Anhui Province has trended to be stable and the bank collapse has been checked to some

    extent. However, the concomitant river siltation seems to expand. In order to find out the present situation of

    sedimentation along the Yangtze River in Anhui Province, this paper made an interpretation and analysis of the Yangtze

    River sandbank and lake reclamation using ETM satellite images from 1987 to the autumn of 2001 in combination with TM

    satellite images and airborne data obtained in this area since 1980. The results provide the basic information for

    harnessing the Yangtze River flood and solving environmental geological problems.

    Abstract   HTML   PDF (1216KB) ( 1449 )

    During the geological remote sensing investigation and monitoring of Yangtze River Valley, the authors carried

    out the survey and research on geomorphology, Quaternary geology and neotectonic fracture at the 1∶250 000 scale by using

    the Landsat ETM images acquired around 2000. Detailed remote sensing investigation at the 1∶50 000 scale was conducted in

    an important area of Dongting Lake by using aerial photos, ALOS, SPOT and other high-resolution data. The investigation and

    comprehensive analysis show that Jianghan-Dongting Basin is a rift basin formed in late Yanshanian-Cenozoic period. It was

    on the whole in the subsidence state because of differential elevation causing the formation of the sub-Huarong uplift in

    the interior of the basin, which extensively deposited river lacustrine facies, alluvial facies and foothill facies

    Quaternary strata in mountain areas. Quaternary sedimentation within the basin is basically continuous deposition. The

    upwelling areas around Jianghan-Dongting basin are characterized by intermittent uplift. Neotectonic movement mainly finds

    expression in uplift, depression, tilting and fracturing. The structural subsidence and uplift of the surrounding mountains

    are controlled by the fractures on the edge and in the interior of the basin.

    Gorges Reservoir are obvious. All this indicates the evolution regularity of erosion and deposition in the Dongting Lake,

    that is, the East Dongting Lake will continue to become smaller, but the speed will slow down;the South Dongting Lake will

    experience deepened scouring, but the area will not become smaller; and the Muping Lake will remain in the original scour

    state and continue to suffer silting up, but the speed will slow down. The environmental problem in the Dongting Lake will

    become the problem of lower water level and decreased ground water level in dry season instead of the floods and siltation.

    REMOTE SENSING FOR LAND & RESOURCES. 2010, 22 (s1): 144-147.   DOI: 10.6046/gtzyyg.2010.s1.30
    Abstract   HTML   PDF (735KB) ( 1325 )

     Based on MSS, ETM+ and 2006 satellite CBERS-2 satellite images obtained in 1975, 2000 and 2006, the authors

    studied the changes in wetland areas of the total basin during the 31 years of 1975~2006. The survey reveals that the

    total area of the wetlands steadily decreased from 1975 to 2000, with the total reduced area being 1 388.50 km2. The

    results also show that, from 2000 to 2006, the area of the wetlands increased from 80 762.13 km2 to 81 825.15 km2. The

    shrinkage of Yellow River Basin wetlands year by year has led the authors to believe that the geological background and

    climate factors of the working area determine the overall distribution and changes of the wetlands, and that human factors

    also play an equally important role in the variation of the wetlands.

    Taking Caofeidian area in Hebei Province as the study area and based on the remote sensing data of Landsat-5 TM

    acquired in 1993 and ALOS acquired in 2007, the authors analyzed the temporal and spatial variations of surface geological

    environmental elements. Some conclusions have been reached:(1) The areas of the delta wetland,agriculture land of non-

    wetland and residential and industrial land were 32.3×104 hm2,20.6×104 hm2 and 4.21×104 hm2 in 1993, and 27.7×104 hm2

    ,21.8×104 hm2 and 6.8 ×104 hm2 in 2007, respectively. During the 14 years,the area of wetland decreased by 77.3%,while

    the agriculture land of non-wetland and residential and industrial land increased by 5.6% and 61.6% respectively. (2) From

    1993 to 2007, the coastline varied obviously. The eastern coastline invaded the mainland with the largest invasive

    distance up to 500 m. On the contrary,the western coastline moved back to the sea with the largest retreated distance up

    to 1 000 m.

    An Analysis of the Effect of Peculiar Geological and Geomorphologic Conditions on Water Erosion Desertification in Guangxi
    CHEN Hua, SONG Zhi-Hong, WANG Yong-Jiang
    REMOTE SENSING FOR LAND & RESOURCES. 2010, 22 (s1): 169-173.   DOI: 10.6046/gtzyyg.2010.s1.35
    Abstract   HTML   PDF (854KB) ( 1801 )

     Guangxi is one of the less developed areas in China. With increasing population and accelerating regional

    exploitation, water erosion desertification has become increasingly serious. The peculiar lithology and structure of

    Guangxi are likely to form specific physiognomy. This paper holds that there exists direct effect of physiognomy, lithology

    and structure on water erosion desertification in Guangxi, with the physiognomy being the primary factor in this aspect.

    Based on GIS analysis, the authors have found that the water erosion desertification is mostly distributed in such  areas

    as carbonate, granite, mudstone and gritstone. The area of carbonate is most serious in this aspect, possessing 46% of the

    total desertification area. This paper has analyzed the lithology, structure, physiognomy of the desertification area. Some

    logical control countermeasures are also put forward in this paper.

     Based on large quantities of remote sensing data as well as topographic and tidal data, this paper studied the

    evolution of the shoreline in China since 1975. The results show that the most typical coast is distributed in the three

    economic zones. The mangrove coast is mostly distributed in the Zhujiang Delta Economic Zone, and the total length of the

    coast had been shortening from 1975 to 2006. Different typical shorelines have different evolutionary characteristics. The

    natural shoreline has been shortening in the past three decades, whereas the man-made shoreline has been extending since

    1975.

    Abstract   HTML   PDF (1567KB) ( 1812 )

     Based on large quantities of remote sensing data and topographic data, this paper studied the evolution of the

    shoreline in Zhujiang Bay since 1978. The results show that the evolution of the shoreline on the east bank and that on the

    west bank had different characteristics from 1978 to 2003, and the shoreline has been mainly man-made since 1978. Zhujiang

    Delta in South China has the largest area of mangrove wetlands in China. However, the mangrove wetlands largely disappeared

    because of intensified human activities in the study area. from 1978 to 2006. The analysis clearly shows the fluctuations

    of the areas of mangrove wetlands in the past three decades. Many natural mangrove forests have disappeared because of

    reclamation projects. Only those in the reserve areas, such as mangrove forests in Qi’ao Island, Futian, and Maipo, have

    been well protected under strict conservation policies.

    REMOTE SENSING FOR LAND & RESOURCES. 2010, 22 (s1): 185-190.   DOI: 10.6046/gtzyyg.2010.s1.38
    Abstract   HTML   PDF (930KB) ( 1138 )

     Wetland has various ecosystems functions as well as economic and social values and hence is regarded as a mature

    resource treasury and living environment for people’s existence and development. In recent years, due to economic

    development and population growth, the human interference and destruction of the wetlands have become increasingly serious,

    and the prevention of the degradation of wetlands has become a very important and urgent task. In this paper, the wetland

    resource in Yancheng was extracted by using multi-source remote sensing data of CBERS, ETM, TM, MSS, in combination with

    other non-remote sensing data, such as the terrain map. According to the information retrieval results, the authors

    analyzed and forecast the change of wetland landscape by using the Markovian models, the Convertion Marix and the Dynamics

    Rate. Based on data available, the authors hold that such changes in the landscape pattern is attributed to some natural

    changes and human activities, such as geotectonic movement, climate, economic development and population growth, with the

    human activities being the main factor responsible for landscape pattern variation.

    Abstract   HTML   PDF (713KB) ( 1101 )

     Due to human activities and natural disturbance, the barren hills as a typical degradation ecosystem are

    constantly increasing. On the basis of geological environment remote sensing survey in eastern China,the authors have

    found that in the Yangtze River Delta Economic District there exist extensive barren hills with miscellaneous heaths and

    bushes under no management, which are mainly distributed in most areas of Zhejiang and north and southwest parts of

    Jiangsu Province. According to the statistical information of the landscape,there exist 43 800 km2 barren hills in

    Zhejiang Province. Field investigation reveals that at least 1/3 of hilly vegetation,i.e., about 14 600 km2 (close to the

    current area of Beijing) of such vegetation, has been severely damaged, unattended and in a state of natural recovery. If

    the economic forest-building is carried out,the barren hills can be restored, and the tremendous economic value can be

    achieved as well.

    REMOTE SENSING FOR LAND & RESOURCES. 2010, 22 (s1): 213-218.   DOI: 10.6046/gtzyyg.2010.s1.44
    Abstract   HTML   PDF (799KB) ( 1587 )

    Based on remote sensing images of 1975(MSS), 2000(ETM) and 2007(CBERS-2), this paper interpreted lake wetland,

    marsh wetland, river wetland and cultivated land of Bosten Lake at the scale of 1∶50000. Some conclusions have been

    reached:The areas of lake wetland, marsh wetland and river wetland have decreased gradually, while cultivated land has

    increased significantly in the past 32 years. During the period from 1975 to 2000, the areas of lake wetland and total

    wetlands increased by a small margin, and cultivated land increased by 454.52 km2, but marsh wetland and river wetland

    decreased by 23.71 km2 and 18.44 km2 respectively. The resources of wetlands were destroyed seriously from 2000 to 2007.

    During these 7 years, lake wetland, river wetland, marsh wetland and total wetlands decreased considerably whereas

    cultivated land increased by more than 526.55 km2. The deterioration velocities of marsh wetland and river wetland were

    37.13 and 5.24 times higher than the velocities during 1975~2000. Natural factors and human activities were two important

    factors responsible for the serious degradation of wetlands. Wetland-agriculture and wetland-desertification constituted

    two processes of wetland degradation.

    Variation of Wetland Landscape Pattern and Its Ecological Effects in the Green Corridor of the Arid Inland in Northwest China:a Case Study of the Lower Reaches of the Qarqan River
    ZHU Gang, GAO Hui-Jun, ZENG Guang, JIN Mou-Shun
    REMOTE SENSING FOR LAND & RESOURCES. 2010, 22 (s1): 219-223.   DOI: 10.6046/gtzyyg.2010.s1.45
    Abstract   HTML   PDF (561KB) ( 1096 )

    Using “3S” technology, the authors carried out research on the changes of the wetland landscape pattern of the

    green corridor in the lower reaches of the Qarqan River based on the diversity index, dominance index, fragment index and

    patch shaped index from 1975 to 2007. Some conclusions have been reached: the wetland area and patch amount increased a

    little from 1975 to 2000 and decreased greatly from 2000 to 2007. In the past 32 years, the average area of the patch and

    the patch density have been reduced continuously, and the patch shape turned to complex; the diversity of the landscape

    pattern decreased, but the dominance and the fragmentation increased; in all the wetland types, the change range of the

    river wetland area was small, the lake wetland area increased greatly, and the marsh wetland area decreased considerably.

    The variation of the wetland landscape aggravated the sandy desertification and led to the reduction of biodiversity, but

    it guaranteed agricultural water demands and ecological water demands, which would be favorable to the stability of the

    Qarqan River green corridor ecosystem.
