摘要
基于国内外关于农业灌溉用水效率评价的已有研究,在明确区分灌溉技术效率和灌溉经济效率的前提下,分别对国外和国内研究现状和进展进行归纳,进而总结灌溉效率影响因素的相关研究。最后,指出了已有研究的不足之处和今后需要进一步研究的重点问题。
Based on the existed domestic and torelgn researcneb on distinction between irrigation technical efficiency and irrigation economic efficiency is given, which is as the premise to respectively discuss foreign and domestic research status and progress. Then factors effeeting irrigation efficiency from the related researches are summarized. Finally, the shortages of the existed researches and the important issues that needed to be researched in the future are pointed out.
