中文摘要：

为有针对性地提升黑龙江省不同地区灌溉水利用效率,本文对黑龙江省灌溉水利用效率的影响因素进行研究.将灌溉水利用效率作为因变量,选取8个主要影响因素：降雨量、腾发量、节水灌溉面积比率、渠系衬砌比率、灌区工程完好率、渠系结构复杂度、灌区工程配套率、灌溉用水量作为自变量,分别建立最小二乘法回归模型（OLS）和地理加权回归模型（GWR）;从全局和局部角度,分析各影响因素对黑龙江省灌溉水利用效率的影响程度.结果表明：黑龙江省灌溉水利用效率及其影响因素的空间自相性随距离增大而减小;全局分析中,除渠系结构复杂度、灌溉用水量与灌溉水利用效率呈负相关,其它影响因素与灌溉水利用效率呈正相关;局部分析中,各影响因素的回归系数空间分布规律明显;GWR模型由于考虑了空间因素,拟合度高于OLS模型.研究结果为黑龙江省不同地区灌溉水利用效率的提升提供了理论参考.

英文摘要：

In order to improve the irrigation water use efficiency in different regions of Heilongjiang Province,the influence factors of irrigation water use efficiency in Heilongjiang Province were studied. Build the models of OLS and ,GWR respectively in which the irrigation water use efficiency was the dependent variable, and the rainfall, the evapotranspiration, the water saving irrigation area ratio, the channel lining ratio, the irrigation engineering intact rate, the canal system complexity, the irrigation engineering equiping rate and the irrigation water quantity were independent variables. Analysed the impact of the influence factors on irrigation water use efficiency in Heilongjiang Province from both global and local perspective respectively. The results showed ： The space autocorrelations of the irrigation water use efficiency and its influence factors decreased with the increasing of distance;In global analysis, the irrigation water use efficiency had negative correlations with the canal system complexity and irrigation water quantity, and had positive correlations with the other influence factors;In the local analysis, the spatial distribution law of each influence factor＇ regression coefficients was obvious ;The fitting degree of GWR model was higher than that of OLS model because of joining the space position. The research results provided a theoretical different regions of Heilongjiang Province. basis for improving irrigation water use efficiency in
