持续干旱与华北水危机

Sustainable drought and water crisis in North China

20世纪80年代以来,华北地区气候持续干旱,水资源供需矛盾加剧,生态环境严重恶化,对我国经济社会可持续发展影响巨大。因此,必须进一步研究以下几方面的问题:一是水资源量的复核和衰减原因分析,二是水资源的合理配置,三是地表水、地下水和外调水的合理配置,四是海水淡化和利用,从而为缓解华北地区的水危机提供了科学对策。

Huanghuaihai Plain is the largest plain in China,whose water is supplied by Yellow River、Huaihe River and Haihe River.Since the80's of 20th Century,the climate is continuously dry in North China,the contradiction of water supply and water demand aggravates,and ecological environment severely deteriorates,which brought the tremendous impacts on national economical and social sustainable development.This severe situation of water resources not only deepens the understanding of serious shortage of water resources in North China,but also shows the direction for further research on lessening water shortage in North China.
