The Analysis on Dynamic Changes of Land Desertification and Salinization Based on RS and GIS

Abstract:

Abstract:For studying the characters of dynamic changes of land Desertification in Songnen Plain, this paper makes use of remote sensing data and geography information system technology and introduces some characteristic parameters, such as the degree of desertification change, to get the numerical value of these characters. The research result shows that: in 1975-1988, the land area of desertification increases rapidly; the deterioration in the border region of land desertification is stronger than that in the center; and in 1988-2001, the area of desertification decreases slowly, the reversion in the border of desertification is stronger than that in the center, then the tendency of expansion of land desertification been initially contained.
