Abstract:In today's world is soil salinization in desert land is land to survive and all its social activities of the basic conditions and the main types of land degeneration is one of the world's resources and ecological problems.Therefore, more accurate analysis soil salinization of space mutation characteristics and variation scale, reveal its distribution to control regional soil salinization has important significance.This paper firstly proposes salinization related concepts; Then on to PingLuoXian regional geomorphic, climate condition, soil type, hydrology, and vegetation make a simple generalization, Then the causes of soil salinization of soil salinization and remote sensing technology and methods of interpretation is elaborated, summarizes PingLuoXian obtained nearly ten years of soil salinization, and its change trend is analyzed and illustrated; Finally make a brief summary and put forward in soil salinization in remote sensing application prospect.
