摘 要: 基于柳园口灌区1985年至2000年资料,采用首尾法计算灌溉用水效率(irrigation water use efficiency,IWUE),以及主成分分析法分析灌溉用水效率影响因素的规律和影响程度。结果表明:实际灌溉面积、井灌引水量比例以及累计资金投入量等因素对IWUE成正贡献率,灌区地下水位成负贡献率;柳园口灌区井灌IWUE高于渠灌IWUE.
关 键 词: 水利水电工程;灌溉用水效率;影响因素;主成分分析

Abstract: Based on the data of Liuyuankou irrigation district from 1985 to 2000, the irrigation water use efficiency (IWUE) was calculated with the net irrigation water use and gross irrigation water use. According to the IWUE and impact factors of different years, the impact laws and degree of different factors which affect the IWUE were investigated with principal component analysis. The results showed that area of irrigation, water diversion ratio base on well and capital input in Liuyuankou irrigation district have greater positive contribution rate to the IWUE, and groundwater level has greater negative contribution rate. IWUE of well irrigation is higher than that of canal irrigation.
Key words: water resources and hydropower engineering; irrigation water use efficiency; impact factors; principal component analysis
