对沙漠化成因机制和治理途径的思考

我国土地沙漠化经过近半个世纪的研究与治理，目前沙漠化土面积仍然在以每年２４６０ｋｍ＾２的速度扩展，而且还有加速扩大的趋势。这就要求我们对以往沙漠化的研究治理进行反思，寻找它的症结所在。现代沙漠化主要是由于人的过度经济活动对资源的破坏造成的。其根本原因是由于人口压力过大。本文通过对沙漠成化因机制和当前沙漠化治理症结的分析，提出了沙漠化治理的新思路。

Study on Cause Mechanism and Rehabilitative Approachesof Desertification in China

Although the work of research and rehabilitation of land desertification in China have passed half a cnetury, the desertified land, however, is still spreading at 2460 km2 annually, and still have the trends of accelerate deterioration. Therefor we are required to look back the former research and rehabilitation work we have done, and to find the sticking point of the land desertification. Contemporary desertification is caused moustly by undermine of human livelihoods to natural resource, and the essential reason is the excess pressure of population. With the analysis of the cause mechanism of desertification and the sticking point of current rehabilitative approaches, in this article, we brought forward a brand-new methodology of desertification rehabilitation.
