西北地区水资源承载能力研究

Research on Some Questions Concerning the Load Capacity Analysis of Water Resources in the Northwest Region of China

通过分析西北地区的水资源量、可利用量、人类生存发展对水资源的需求 ,提出了西北地区人口承载量 ,对西北地区的水资源承载能力进行了评价。从评价结果来看 ,西北地区黄河流域、河西地区和新疆的东疆地区将出现人口超载 ,超载的原因是水资源紧缺 ,尤其是在人口密度较大的区域水资源更为紧缺 ,人口和经济发展对水资源的需求超过了水资源的承载能力。

The largest population load is calculated and the load capacity of water resources in Northwest Regions of China is evaluated by analyzing the water resources, the potential water supply, the demand of human being and its development. The results indicate that the overload of population will occur in Yellow River basin, Hexi region and east region of Xinjiang province, because the water demand of population and economical development exceed the potential water supply.
