我国位于东亚季风气候区,加之三级阶梯的地形地貌格局,水资源具有显著的时间和空间分异特征,基础条件十分复杂;随着经济社会的发展,行业间、区域间用水的竞争特性持续增强,水污染与水生态退化问题凸显。与此同时,我国的水利基础设施仍然较为薄弱,对水资源配置和综合利用的支撑能力有限。我国是世界上水资源问题最为复杂、应对最为困难的国家,
China is located in the monsoon climate zone of East Asia, combined with topographic and geomorphological patterns of three steps, water resources have significant temporal and spatial differentiation characteristics, and the basic conditions are very complicated. With economic and social development, the competitive characteristics of water among industries and regions continue to increase , Water pollution and aquatic ecological degradation highlighted. At the same time, China’s water infrastructure is still relatively weak, and its capacity to support water allocation and comprehensive utilization is limited. Our country is the country with the most complicated water resources problem and the most difficult response to it.
