    THE COMPARISON BETWEEN IMAGE SIR-A AND MSS IN DIFFERENT AREA IN CHINA
    Shi Jizhong
    REMOTE SENSING FOR LAND & RESOURCES. 1996, 8 (4): 1-8.   DOI: 10.6046/gtzyyg.1996.04.01
    Abstract   HTML   PDF (5162KB) ( 984 )

    By comparing between image SIR-A and image MSS in different area such as Luobubo,Huabei plain, Luliang mountain, Badanjilin sand desert and Xinjiangkeping area, this paper sums up the imagery feature of wind abrasion landform, plain river, villages and small towns, loess plateau, sand desert and rock on that two images, and analyses preliminarly that two images imaging mechanism, and points out the difference between two images interpret effect and pre-sents reference to anyone when he selects information source.

    STUDY ON THE WETLAND CLASSIFICATION OF GUANGDONG PROVINCE BY REMOTE SENSING TECHNIQUE
    Huang Huiping
    REMOTE SENSING FOR LAND & RESOURCES. 1996, 8 (4): 9-15.   DOI: 10.6046/gtzyyg.1996.04.02
    Abstract   HTML   PDF (395KB) ( 1308 )

    In the light of the situation of the wetland classification of Guandong Province, the method distinguished wetland from the remote sensing image were put forward. based on that, the sys-tem of wetland classification was built up using decomposition and classification method, mean-while, the table of wetland types was work out.

    USING REMOTE SENSING TECHNOLOGY TO MONITOR AND RESEARCH TROPICAL PRIMEVAL FOREST IN JIANFENG MOUNTAIN, HANINAN, CHINA
    Li XueQian
    REMOTE SENSING FOR LAND & RESOURCES. 1996, 8 (4): 16-22.   DOI: 10.6046/gtzyyg.1996.04.03
    Abstract   HTML   PDF (1099KB) ( 935 )

    This paper introduces in brief reflecting spectrum feature of different woods in national forest of Jianfengling of Hainan Province, according to that, using TM data to class and calculate the area to every forests. By contrast the area of different classification of different time. It surveys clearly some forests field changing, especially the cases of primeval forest is reducing constantly, so it provides some information for managing and protecting to primeval forest.

    PRELIMINARY ANALYSIS OF THE ABNORMAL IMAGERY FEATURE OF VEGETATION LANDSCAPE AND THE REASON CAUSED BY IN THE GOLD DEPOSICTS OF QINLING OF CHINA
    Ma JianWei, Xu RuiSong, Ao HeHui
    REMOTE SENSING FOR LAND & RESOURCES. 1996, 8 (4): 23-29.   DOI: 10.6046/gtzyyg.1996.04.04
    Abstract   HTML   PDF (1325KB) ( 895 )

    This paper introduces in briefly some vegetation Landscape abnormal and its imagery features which related to altered rocks of the gold deposits and combines biology with some results of vegetation reflection spectrum studying to analysing in preliminarily the reason of geochemistry abnormal and some vegetation reflection spectrum abnormal.

    THE EFFECT OF REMOTE SENSING AND GEOCHEMICAL EXPLORATION IN OIL AND GAS PREDICTION
    Tan Qing, Wu Yajun, Chen Changsheng
    REMOTE SENSING FOR LAND & RESOURCES. 1996, 8 (4): 30-35.   DOI: 10.6046/gtzyyg.1996.04.05
    Abstract   HTML   PDF (337KB) ( 798 )

    The information of hidden structures from remote sensing and the hydrocarbon anomaly from geochemical exploration was analysed and used in the prediction of hydrocarbon-bearing target areas. This technique obviously improved the effect of-geological interpretation of the anomaly.

    A NEW METHOD TO INVESTIGATE THE SOIL EROSION INTENSITY IN LOSS HILL AREA
    Zhang Bing, Wang Xiangjun, Tong Qingxi
    REMOTE SENSING FOR LAND & RESOURCES. 1996, 8 (4): 36-39.   DOI: 10.6046/gtzyyg.1996.04.06
    Abstract   HTML   PDF (184KB) ( 1225 )
    Thick gullies are the results of soil erosion in the loess hill area. On the contrary, gully density could also embody the intensity of soil erosin. Linear extraction technique and a density statistical software have been developed to make a gully density map directly from TM image. By building a regression function between gully density and soil erosion intensity, the gully density map can be transfered to soil erosion intensity map. This method is very suitable for quick investigation of soil erosion in the extensive loess area.

    A STUDY ON DYNAMIC CHANGES OF RICE REFLECTIVE CHARACTERISTICS IN GROWTH PERIOD
    Shen Zhangquan, Wang Ke, Wang Renchao
    REMOTE SENSING FOR LAND & RESOURCES. 1996, 8 (4): 40-44.   DOI: 10.6046/gtzyyg.1996.04.07
    Abstract   HTML   PDF (272KB) ( 1082 )
    With the systematic research of canopy reflective alternation during early rice growth period, the results could be summarised as follows: 1.The RVI value varied regularly during growth period. Before heading, with days increasing after trasplanting, RVI value increased straightly, and it reached the maximum value just before heading; howerver, after heading, RVI value decreased with the days increasing after trasplanting. 2.There existed closely relation between accumulated temperature and RVI value. According to linear regression analysis about accumulated temperture and RVI value, it was found that: Before heading, they had marked positive relation, and in the other hand, they had notable negative relation after heading. These results maybe useful to correct the error of growth stage and improve the accuracy of yield estimation in yield estimation by remote sensing.

    THE STUDY AND APPLICATION ON AUTOMATIC EXTRACTING OF THE ANOMALOUS INFORMATION OF REMOTE SENSING OF GOLD DEPOSITE
    Zhu Jiawei, Zhang Tianyi, Sheng Jihu
    REMOTE SENSING FOR LAND & RESOURCES. 1996, 8 (4): 45-50.   DOI: 10.6046/gtzyyg.1996.04.08
    Abstract   HTML   PDF (360KB) ( 1044 )
    Based on the studying of reflecting spectrum feature of some material in Xiongershan in West Henan.In this paper, a new method for extracting the anomalous information (hydro-thermal alteration information and poisonlized plant information) of remote sensing of gold deposite automaticly from Landsat TM data is developed.As there are no influence caused by vegetation in extracting the imformation that talk above, this method can be applied in any regions being covered with different degree of plant. The great successes have been achived in seeking gold deposite in Xiongershan in West Henan.

    GOLD MINERALIZED ALTERATION ENHANCEMENT AT MODERATELY VEGETATION COVERED AREA BY USEING LANDSAT TM AND JERS-1 OPS DATA
    Zhang Manlang
    REMOTE SENSING FOR LAND & RESOURCES. 1996, 8 (4): 51-56.   DOI: 10.6046/gtzyyg.1996.04.09
    Abstract   HTML   PDF (1189KB) ( 927 )
    This paper analysed the feature of absorption spectrum of alteration mineral that relating to the gold mineralized alteration such as the ferraus, the clay and the carbonete, and the spectrum disturbance caused by vegetation covered the gold deposite area. Meanwhile, it introduced how to use the methods of the vegetation index, the radio-PAC and the vegetation masking to extract the information of gold mineralized alteration from Landsat TM and JERS-1 OPS data while the vegetation information was constrained.
