摘要
本文对我国土地沙漠化现状与发展趋势进行了全面分析,较完整地论述并给出了我国沙漠化态势的基本轮廓。目前,我国共有沙漠化土地20.1万km2,沙漠化所涉及的我国北方212个县(旗、市)的沙漠化程度分别是154个轻度、35个中度和23个重度。预测到本世纪末,我国沙漠化土地面积将扩大到23.3万km2,212个沙漠化县(旗、市)的沙漠化程度将发展为76个轻度、93个中度和43个重度。
This paper first studies completely quantitative and qualitative aspects of status and trend of desertification in China and analyses its basic characteristics. Now, the area of desertification is 201 thousand km2, the desertification degrees of 212 counties affected by sandy desertification in China are: 154 slight degree counties, 35 middle degree counties and 23 severe degree counties. It is predicted that the area of desertified land will be 233 thousand km2 in 2000, the desertification degrees of 212 counties will become 76 slight degree counties, 93 middle degree counties and 43 severe degree counties.
