我国节水农业发展现状研究

摘要

The utilization coefficient of irrigation water in China is 45%,far behind the 70% of developed countries;The efficiency of national agricultural water is low,the unit grain yield water of developing countries is 2.5-3 times higher than developed countries.Therefore,the development of water-saving agriculture in China has a crucial significance.This paper based on the current situation of China＇s agricultural development,combined with the layout of the development of China＇s water-saving agriculture,focusing on analysis of technical,institutional,financial and policy aspects of five major water-saving agricultural areas,review and exchange of successful experience developing water saving agriculture,analysis of its shortcomings and put forward countermeasures to promote water-saving agricultural development.%中国的灌溉水利用系数只有45%,大大落后于发达国家的70%;全国农业用水效率较低,单位粮食产量耗水量比发达国家高2.5～3倍。所以我国发展节水农业具有至关重要的意义。本文根据我国农业发展现状,结合我国节水农业发展布局,重点分析5大节水农业区在技术、制度、资金和政策等方面的节水农业现状,总结交流发展节水农业的成功经验,分析其存在的不足,从而提出更好的促进节水农业发展的路径。
