摘要: 我国目前有近300个城市缺水,缺水问题己成为城市经济建设发展的重要制约因素之一。城市经济建设的持续发展影响着全国经济建设顺利发展的进程,所以,解决好城市缺水问题则成为关系到全局的重大课题。今后应进一步提高水的利用效益,在全面节流的基础上多途径开源。不断提高工业用水的重复利用率,并控制水污染,加速实现城市污水资源化。应制定鼓励节约用水的技术经济政策,支持节水型设备改造,调整产业结构和工业布局。缺水城市要限制需水多的行业发展。

Abstract: The crisis of water resource is an inriportant knotty problem which puzzles many countries of the world. Particularly, the lack of water in cities becomes more and more severe. At present,there are 300 cities in China which lack water. In the 30 cities having a population of more than one million this problern is especially striking. The problem of lacking water has become one of the important restraining factors of economic development and construction in cities. The conditions of water resource in China are not superior. The water resource is more insufficient in large areas of the north of China ,where the speed of economic development of many cities surpasses the carrying capacity of local water resource. In the future, it should be that raising the utilization benefits of water, adopting vigorous measures to tap new water source, improving the repeated utilization rate of the production-use water,and controlling the pollution of water. Also it should be that making the technique and economy policies to inspire the economic use of water, supporting the transformation of the water economizing equipments, and adjusting the structure of property. In the cities which lack water the development of the industries that demand great amount of water should be limited.
