摘要
文章从水性质特点谈到中国水资源的问题 ,认为不能单纯用年平均降雨量的多少来判定中国水资源的状况 ,水资源开发利用的好坏决定于人类社会的调节和管理。中国水资源总的来说是够用的 ,最大问题是降水量的时空分布不平衡。中国农民几千年来创造了许多治水蓄水用水的经验。农业节水非常重要 ,关键在“分散蓄水 ,分散使用” ,以减少径流在汇集和分散过程中的损失和污染 。
The Characteristics of water and the issue of water resources in China are mainly discussed in the paper.The viewpoint that the situation of water resources in China cann't be judged simplily by the amount of average yearly precipitation,and the exploitation and utilization of water resources depend on the humen's control and management are expounded.In general the water resources in China is enough for using,its unbalnced distribution in space time is the most problem.Lots of experiences about bringing water under control and using water were accumulated by the Chinese farmers in thousand years histroy's practice.Saving water in agriculture is very important,the key measure is to advocate “decentralized storage and decentralized utilization of water” so that the loss and pollutiion of runoff can be controled.In order to raise the efficiency of water use,a series of research and practical work needs to be carried out.
