中国农业水资源可持续利用方略

Strategies for Sustainable Use of Agricultural Water Resources in China

针对中国水资源严重短缺、水体污染加剧、"水减粮增"矛盾突出、粮食生产与区域水资源分布错位、"北粮南运"难以为继等重大问题,以农业水资源可持续利用为目标,实施粮食生产区域再平衡战略、强化降水利用的绿水战略和短缺水资源的技术、非常规水、贸易替代方略,同时提出建立与水资源相匹配的种植制度,大力推进节水农业科技创新、升级节水灌溉技术、建立水资源转移补偿机制、改变膳食结构等建议。

Aims to solve the problems of severe scarcity of water resources, water pollution, a contradictionbetween the decline of water use and grow of grain demand, a mismatch between grain production and waterresource distribution and unsustainable transport of grain from north to south, we put forward agricultural waterresource sustainable use strategies including regional rebalance of grain production according to water resources,green water strategy（effective use of precipitation） and water resource replacement by technology,unconventional water and international trade. At the same time, we proposed several proposals such asdeveloping cropping systems adapted to water resource, strengthening technological innovation for water-saving agriculture, upgrading water saving irrigation technology, setting up compensatory mechanisms for ashift of agricultural water uses and improving dietary pattern.
