干旱地区有两个显著特点 ,一是水资源极度贫乏 ,二是生态环境极度脆弱。干旱内陆地区要实现绿洲持续发展 ,必须走节水增效的生态型绿洲之路。从河西内陆河流域的水资源特点出发 ,分析论证了河西地区实施节水灌溉与社会经济、生态环境协调发展的关系 ,提出了三大流域 :石羊河、黑河、疏勒河的绿洲可持续发展模式 ,可供水管理者决策参考。
There are two distinguishing features in arid areas. First, water resources are extremely poor. Second, the ecological environment is extremely fragile. Arid inland areas to achieve sustainable development of oasis, we must take the road to save water and increase efficiency of the oasis. Based on the characteristics of water resources in the Hexi Inland River Basin, the relationship between the implementation of water-saving irrigation and the coordinated development of social economy and ecological environment in Hexi area is analyzed and demonstrated. The three major river basins are proposed: oases of Shiyang River, Heihe River and Shulehe River Sustainable development model, water supply managers can make decisions.
