- Abstract:
-
Desertification of west Liaohe River basin became serious in recent years due to fragile ecological environment, abundant land use types and the further development of social economy, which is fearfully constraining the stability of social economy and sustainable development. By using TM image data in the late 1980’s and 2000 as information sources, based on the data extraction of the two-period sandy desertification, this article has thoroughly analyzed the situation of sandy desertification in west Liaohe River basin. Meanwhile, the transformation proportions among different desertification lands over the past ten years were calculated. By adopting transfer matrix method and mathematical model method, it presented the transfer matrix and dynamic degree of sandy desertification lands in the late 1980’s and 2000. It turned out that wind erosion desertification had been basically brought under control, water erosion desertification lands had increased by almost 1.5% and salinization land had reduced slightly.
