随着国民经济的发展,人们对水量和水质的需求不断增长提高,而环境污染却在不断加剧,使得水资源供需矛盾日益突出。水资源已成为经济发展的重要制约因素。因此,对水资源系统的综合利用问题讲行系统地研究是非常必要的。 With the development of the national economy, people’s demand for water and water quality continues to increase and the environmental pollution is steadily increasing, making the contradiction between supply and demand of water resources increasingly prominent. Water resources have become an important constraint on economic development. Therefore, it is necessary to systematically study the problem of comprehensive utilization of water resources system.
