水资源危机论

水既是战略物资又是生命的基础。水资源的安全关系到社会可持续的发展,关系到人类自身的生态系统的生存和发展,关系到国家的稳定、主权和安全。全球人口的增长、气候变暖、环境污染的加重、城市化进程的加快等都是影响水资源质和量的关键因素。全球水资源随着时间的推移日趋紧缺乃至危机;天然水分类表明,淡水资源是水资源最重要的成分。含有害成分的淡水资源是地方病的致病因素。中国水资源虽然不算少,但人口13亿,人均水资源量排在世界第128位,属于贫水国,并且水资源时空分布不平衡。面对中国淡水资源严重短缺问题,动员全民节水是现实可行的,但学习国外先进治水经验,加强水资源管理的国家级决策至为关键。

WATER RESOURCES CRISIS

Water is strategic material, and also is base of life. The security has close relations to the continuable development of the society, to the human ecosystem, to the national stabilization, sovereignty and security. Global population growth, warmer climate, more serious environmental pollution, quickened urbanization, etc, those are the factors affect its quality and quantity. Freshwater containing damaging element can induce endemic. Although it has big water gross, with 1,300,000,000 people, resource for per capita ranks at 128 in the world. So, for China, water is insufficient. Moreover, it has spatiotemporal unbalanced distribution. To solve the freshwater shortage, it is practical and feasible to mobilize the whole people to save on water. At the same time, it is critical to study the foreign advanced water-control experiment and strengthen water resource management.
