Abstract:

The fact of global warming and the effects on ecological environment，society and economy in Gansu province in the background of global warming are analyzed with the interrelated materials in this paper.
The countermeasures against climate change andsustainable development are shown too.And those，to Gansu province，can be summed up as two primary problems.First is water problem.Water problem is primarily to utilize reasonably，manage efficiently，save water，exploit and utilize water resources by precipitation enhancement over the Mountain Qilian. Second is sand problem.The problem is crucially to hold back the process of desertification.As this paper’sview，this holding back can be realized by the optimum project for recovering vegetation which would be abstract edby quantitatively calculating the categories distribution，run and carrying capacity of local forest and grassp lanted by using Regional Climate-Ecology Mode according to ecological environment sincluding terrain，physiognomy，climatehydrology，soil and so on.

Key words: globa lwarming, ecological environment, society-economy

摘要：

根据相关资料，分析了全球变暖的事实以及在全球变暖的大背景下对甘肃省生态环境和社会、经济的影响，并提出了应对气候变化、实现可持续发展的对策。这些对策对甘肃省而言，归纳起来主要是两个问题：一是用好水、管好水、节约用水，开发利用祁连山空中云水资源，实施人工增雨（雪）；二是沙的问题。关键是遏制沙漠化进程，使用“区域气候—生态模式”，根据各地的地形、地貌、气候、水文、土壤等生态环境，定量计算各地林、草种植的品种、布局、走向、承载力，以提出恢复植被的最优方案。
