水是自然界中的基本要素,是人民生活和社会生产不可缺少的一项自然资源。随着社会经济的发展、人口增长和人民生活水平的提高,对水的需求不断增加,供需之间的矛盾日趋突出。因此,开展水资源研究工作,使之综合开发,合理利用和统一管理,已成为世界各国普遍重视的问题。在水资源不太富裕和时空分布极不均匀的我国,显得更为重要。水资源调查评价是国家农业自然资源调查和农业区划的重要组成部分,它为江河流域规划、地区水利规划、水资源调水规划、国土整治规划等提供重要的科学依据,是合理开发和科学管理水资源的基础。在我国,系统的水资源调查评价工作,于新中国成立以后即已开始。淮河流域水资源调查评价工作与全国进展相同,并逐步由浅易到深化,取得了重要成果。
Water is an essential element in nature and a natural resource indispensable to people’s life and social production. With the socio-economic development, population growth and improvement of living standards of the people, the demand for water is constantly increasing, and the contradiction between supply and demand has become increasingly prominent. Therefore, to carry out the research on water resources so as to make comprehensive utilization, rational utilization and unified management have become the issues of universal importance to all countries in the world. It is even more important in our country, where water resources are not rich and the distribution of time and space is extremely uneven. The investigation and appraisal of water resources is an important part of the national agricultural natural resources survey and agricultural zoning. It provides important scientific basis for the planning of river basins, regional water conservancy planning, water resources and water diversion planning and land readjustment planning and so on. It is a basis for rational development and scientific management The foundation of water resources. In our country, the systematic investigation and appraisal of water resources started after the founding of new China. Huaihe River Basin water resources survey and evaluation work with the same progress, and gradually from easy to deepen, and achieved important results.
