浅析坝上地区土地沙漠化问题

A superficial analysis on sandy desertification problem in Bashang area

通过对坝上典型调查区沙漠化现状及其发展趋势的调查分析,发现虽然坝上地区生态环境局部好转,但是总体恶化的局面仍然没有彻底改变。探讨了沙漠化成因以及发生发展过程,认为,气候、地貌、沉积物以及水文条件是坝上地区沙漠化的自然基础,而人类不合理的经济活动是沙漠化发生的直接原因。总结了沙漠化对农牧业、交通、水利、通信以及人类健康等的危害,提出防治坝上地区沙漠化的对策建议。

After researches and analysis on status and trend of sandy desertification in Bashang area, the authors found that sandy desertification took a turn for the better in some areas, but it took a turn for the worse in overall situation. The degree of sandy desertification will be exacerbating unless some combating measures are put in effect; Through surveying the causes of sandy desertification and its development, we think that the natural basis of sandy desertification is climate changes, landforms, features of sediment and the condition of hydrology, and its immediate cause is the unreasonable activities of human being. The harms of sandy desertification in farming, stock raising, traffic, communication, water conservancy facilities and the health of human have been summarized in this paper, and some measures and proposal on combating sandy desertification have been put forward.
