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。
Using macroscopic remote sensing information data to interpret macroscopic desertification land in large-scale range, and combining with ground investigation microscopically, the causes of desertification land are comprehensively analyzed and the interaction between development process and succession rule of ground vegetation takes place. The succession stage, composition, structure and distribution of plant communities and their degeneration process have a causal and mutual promotion relationship with the degree of land desertification. This study can provide theoretical basis for vegetation restoration and reconstruction as well as species selection.
