摘要
我国土地沙漠化经过近半个世纪的研究与治理 ,目前沙漠化土地面积仍然正以每年 2 46 0km2 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为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。而沙漠化治理措施恰恰没有从根本上解决这一问题。沙产业理论 ,将沙漠化的防治和发展经济密切结合起来 。
Although the work of research and rehabilitation of land desertification in China have passed half a century, the desertified land, however, is still spreading at 2?460?km 2 annually, and still have the trends of accelerating deterioration. Therefor we are required to look back the former research and rehabilitation work we have done, and to find the sticking point of land desertification. Contemporary desertification is caused mostly by undermine of human livelihoods to natural resource, and the essential reason is the excessive pressure of population. While the current instruments cannot resolve the key problem. The theory of deserticulture will combine the desertification prevention and cure with the economic development tightly, and will provide a brand new method for the desertification prevention and cure and the economic development in China.
