| 摘 要： | 对2007—2012年全国纯井灌区不同类型有效灌溉面积占纯井灌区有效灌溉面积的比例与纯井灌区灌溉水有效利用系数进行多元回归分析,建立了灌溉水有效利用系数模型。结果表明,5种灌溉类型灌溉面积占比对纯井灌区灌溉水有效利用系数的影响程度为:微灌>喷灌>管道输水地面灌>防渗渠道地面灌>土质渠道地面灌;各省、全国纯井灌区灌溉水有效利用系数模拟值与实测值误差分别在±10%、2%以内。

| Abstract: | Multivariate regression analysis was conducted to identify the relationship between irrigation area composition of different irrigation types and irrigation water use efficiency,and irrigation water use efficiency model was established using 2007—2012 nationwide well irrigation data.The results showed that the influence degree of five irrigation types on irrigation water use efficiency in the decreasing order was micro-irrigation,sprinkler irrigation,pipeline water system,surface irrigation of lining canal,surface irrigation of earth canal.Errors between simulated and measured water use efficiency of well irrigation district in each province and in China were with in ±10%,2% respectively. |
