Remote sensing information extraction and analysis on ecological landscape pattern in Tarim River Basin

Wang Ranghui;Zhang Huizhi;You Xianxiang;Peng Ruyan. Xinjiang Institute of Ecology and Geography, Chinese Academy of Sciences, Urumqi,Xinjiang, 830011, P.R.China.  
According to the principles of image and graphics, the image composite models that can better identify information richness should be found in the Tarim River Basin.Based on some remote sensing information sources and GRS99 and IDRISI image processing software, the basic image for landscape pattern analysis is chosen. Both the desert-oil highway and the Tarim River are two big corridors crossed the middle of the area, which decides the transfer ways of substances and energy and information in the whole system. Corridors consist of lines connected with patches of oil fields, which reveals the development path of oil prospecting in the area. The river bank forests make the river corridor abound with ecological significance. Natural vegetations distributed far from the main course form the strip and ellipse as well as other irregular communities, which have improved the contents of landscape. The dunes and desert in the south and northeast are matrixes that decide the fragility in the area. Human activity is the chief reason of land partition and landscape fragmentation. The theory and practice of ecological landscape construction should be guided by remote sensing and GIS as well as some modern science and technology achievements.
