    Abstract   HTML   PDF (1080KB) ( 781 )

    On the basis of analysis of remote sensing image and DEM, and by combining with the cluster analysis of the main factors to the ecological environment, the division and evaluation of ecological environment in Jiangxi province have been done in this paper according to the heterogeneity among landscapes and the similarity of interior landscapes with the principle and method of landscape ecology. All of this provides the objective basis for Jiangxi province government to make a long term planning on the construction of ecological economy, to effectively solve the problems of ecological environment and to make the decisions on the development of social economy and protection of the ecological environment.

    REMOTE SENSING EXTRACTION OF ALTERED INFORMATION RELATED TO GOLD MINERALIZATION, INNER MONGOLIA SECTION, NORTH MARGIN OF NORTH CHINA PLATE
    CHEN Song-ling, LU Fu-hong, GAO Guang-ming, WU De-wen
    REMOTE SENSING FOR LAND & RESOURCES. 2001, 13 (2): 13-18,64.   DOI: 10.6046/gtzyyg.2001.02.03
    Abstract   HTML   PDF (1417KB) ( 895 )

    The essential types of altered rock related to Au mineralization in Wulashan, Maihanshan and Sunitezuoqi and the remote sensing methods to extract them are discussed in this paper. Some image processing methods are applied for extracting the altered information from TM data, such as Ratio, principal component and image classification etc. Field geological survey affirms a excellent concordance between image altered zone and gold mineralization-altered zone, and two large alteration zones are found by remote sensing process.

    AN ANALYSIS OF THE CHANGES AND EVOLVEMENTS ON THE FORESHORE AND DEEP CHANNELS OF LINGDING BAY IN PEARL RIVER ESTUARY
    CHEN Shui-sen, ZOU Chun-yang, LI Xia
    REMOTE SENSING FOR LAND & RESOURCES. 2001, 13 (2): 25-27,42.   DOI: 10.6046/gtzyyg.2001.02.05
    Abstract   HTML   PDF (238KB) ( 923 )

    By means of GIS and remote sensing technique, the changes and evolvements characteristics of foreshore and deep channels of Lingding bay in Pearl River Estuary are analyzed. The change reasons and consequences are also illustrated. Basing this, it reminds us of standardizing the development behavior to the coastal area in favor of the long-term development of Pearl River Delta from the sustainable development high-points of coastal area.

    USING RS AND GIS TECHNOLOGY TO INVESTIGATE URBAN GREEN LAND COVER
    XU Xin-liang, ZHUANG Da-fang, ZHANG Shu-wen, ZOU Ya-rong
    REMOTE SENSING FOR LAND & RESOURCES. 2001, 13 (2): 28-32.   DOI: 10.6046/gtzyyg.2001.02.06
    Abstract   HTML   PDF (1029KB) ( 1042 )

    Urban green land cover is an important part of urban landscape and performs a very important function in urban system. The traditional method for investigating urban green land cover is manual work and there is a lot of shortcoming and deficiency. This paper introduces a new method that using RS and GIS technology to investigate urban green land cover. We can use the data information in GIS that obtained using this method to analyze distribution of urban green land cover. Of course, the information can also help government to plan and manage green land.

    Technology and Methodology
    SPLIT WINDOW ALGORITHMS FOR RETRIEVING LAND SURFACE TEMPERATURE FROM NOAA-AVHRR DATA
    QIN Zhi-hao, ZHANG Ming-hua, Arnon Karnieli
    REMOTE SENSING FOR LAND & RESOURCES. 2001, 13 (2): 33-42.   DOI: 10.6046/gtzyyg.2001.02.07
    Abstract   HTML   PDF (608KB) ( 1155 )
    NOAA-AVHRR has two thermal channels for monitoring the surface temperature of the earth. Split window algorithm is the most common technique for retrieving land surface temperature from AVHRR data. Several split window algorithms have been developed in the last two decades. The purpose of the paper is to introduce these algorithms for the potential users in China,with concentration on the presentation of their detailed computation and comparison of their accuracy in actual application of land surface temperature retrieval.
