水是生命之源,是人类赖以生存和发展的重要物质基础,也是不可缺少、不可替代的战略资源。我国的水资源总量虽居世界第六位,但人均占有量仅2474m~3,仅为全球人均占有量9636m~3的26%,是一个贫水大国。我省的情况也不容乐观。水资源人均占有量虽略高于全国水平达到2800m~3,但干旱、缺水仍是制约我省农业和国民经济发展的瓶颈。加之近年来降水减少,用水增加,污染加剧,使有限的水资源变得越来越短缺。20年前当我们还不怎么关注外部世界的时候,世界上开了两个重要的会议,一个是联合国人类环境会
Water is the source of life, is an important material basis for human survival and development, and is an indispensable and irreplaceable strategic resource. Although China ranks sixth in the world in terms of total water resources, its per capita share is only 2474m 3, only 26% of the world’s average of 9636m 3 per capita, making it a large country that is poor in water. The situation in our province is not optimistic. Although the per capita water resources slightly higher than the national average reached 2800m ~ 3, but drought and water shortage is still constraining the development of our province agriculture and national economy bottleneck. In addition, in recent years, precipitation has been reduced, water use has increased, and pollution intensified, making limited water resources increasingly scarce. Twenty years ago when we did not pay much attention to the external world, there were two important conferences in the world. One was the United Nations Conference on the Human Environment
