皮山县沙漠化机理动态分析

Dynamic Analysis of Pishan County Desertification Mechanism

和田地区位于中国最大流动沙漠——塔克拉玛干沙漠的南部,是我国沙漠化危害最严重的地区之一。本文选取了该地区遭受沙漠化最严重的皮山县作为研究区,对其进行了沙漠化机理动态分析。沙漠化是自然因素与人为因素的耦合作用下形成的,其中,自然因素的影响是缓慢的,是沙漠化形成和集中分布的基础,而人为因素的影响会加快其进程,是沙漠化扩散的主要动力。

Hotan Prefecture is located in China's largest mobile desert- the Taklimakan Desert of southern, is one of the regions with the most serious sandy desertification hazard in China. This paper selects the region suffered the most serious desert Pishan County as the study area, the were desertification dynamic mechanism analysis. Desertification is formed under the coupling effects of natural factors and human factors. Among them, the influence of natural factors is slow, desertification formation and centralized distribution, and the influence of human factors will accelerate its process, and it is the main motive force of the spread of desertification.
