摘　　要：利用遥感信息资料解译宏观的大尺度范围沙漠化土地 ,微观上结合地面调查 ,进行综合分析沙漠化土地成因、发生发展过程与地面植被演替规律的相互作用。植物群落所处的演替阶段、组成、结构与分布以及其退化过程 ,与土地沙漠化程度有因果和相互促进的关系 ,该项研究可为植被恢复和重建及物种选择提供理论依据。By use of remote sense information to explain macroscopic desertization land in large scale, contributing factors and developing progress of desertization land and the interaction between vegetation succession rule have been comprehensively analyzed. The succession period, structure, composition, distribution and degeneration progress of plant community have a relationship of causality and promotion with the degree of land desertization. This research has provided theoretical basis for restoration, replanting of vegetation and selection of species.
