中国水资源的总量约2810×109m3,相当人均水量2730m3,亩均水量1870m3。人均、亩均水量均低于世界平均水平。中国水资源的时空分布不均,水资源和土地资源的组合不相适应。近年来对水的需求增长十分迅猛,水源开发跟不上经济的发展,供需矛盾突出。本文通过对我国水资源的特点、开发利用状况进行剖析,对我国水资源开发利用提出若干建议。
According to recent estimation, the totalL amount of water resources in China is abourt 2816km3, corresponding to 2730m3 per capita and 28000m3 per ha, which are both lower than those of the world average. The water problems of china are due to the uneven distribution of water resources in time and space, and the inconsistent combination of the water and land resources. In recent years, the rapid increase of water demand have brought some serious contradiction between water supply and demand. In this paper, the characteristics of water resources and the present status of water resources development and utilization are discussed, and some suggestions are presented.
