Remote Sensing Monitoring of Soil Salinization in the Delta Oasis of Weigan and Kuqa Rivers
Soil salinization matter is always stratagem problem of sustainable development and improving environment quality in arid area. Soil salinization qua one of soil degenerate form, which has became a global research hot point. Extraction of saline soil information is not only the hot point, but also the difficulty of the special information extraction from remotely sensed images. The research adopt Decision - making Tree classify method, accomplish the automatic extraction of saline soil information based on knowledge; accordingly analysis space time and quantity change character of saline soil. The results indicate that total area of saline soil increase a little in research region from 2002 to 2006, thereinto movement extent of low - grade and mid - grade saline soil are tempestuousness, but all kind of saline soil have change trend of moving to northwest of oasis inside.
