节水灌溉与河西绿洲可持续发展

Water Saving Irrigation and Sustainable Development in Hexi Oasis

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。

In the arid area, there are two obvious characteristics as follows: One is poorest in water resources; another is weakest in ecological environment. For the arid inland area, implementation of sustainable development of oases must take the road of ecological oases with water saving and increasing efficiency. From the characteristics of water resources in the Hexi continental river basin, the coordinative development relationships between implementation of water saving irrigation, social economy and ecological environment are analyzed and demonstrated. The oases′ sustainable development modes for the three river basins of the Shiyanghe, the Heihe and the Shuleihe, are proposed. They will be useful to decision-making of water management.
