人口持续增长、城镇化及工业化建设规模不断扩大,水资源短缺问题愈来愈受到社会各界的高度重视。就社会用水需求而言,其存有很大的区别,用水竞争性日益增强、用水主体日趋多元化。由于农业水资源消耗比例高、获得的经济效益低,其在用水比例方面呈不断下降趋势。此外,农业对水资源的利用主要采取粗放型方式,以致水资源浪费及水资源稀缺之间形成矛盾。如何提高农业用水效率成为摆在我国面前的又一重大课题。文章结合实际,研究了农业用水效率影响因素,并有针对性的提出了政策建议,旨在为有效改善我国农业用水状况、提高水资源利用率等提供参考。
As the population continues to grow, the scale of urbanization and industrialization is constantly expanding. The issue of water shortage is receiving more and more attention from all sectors of society. As far as social water demand is concerned, there is a big difference between them. The competitiveness of water use is increasing day by day. The main water users are increasingly diversified. As the proportion of agricultural water consumption is high, the economic benefits obtained are low, and its proportion in terms of water consumption is constantly declining. In addition, agriculture mainly uses the extensive use of water resources, resulting in conflicts between wasteful water resources and water scarcity. How to improve the efficiency of agricultural water use has become another major issue before our country. Combining with the actual situation, this paper studied the influencing factors of agricultural water use efficiency, and put forward some policy suggestions pertinently to provide a reference for effectively improving the status of agricultural water use in our country and improving the utilization rate of water resources.
