全国纯井灌区类型构成对灌溉水有效利用系数的影响分析
Influence Analysis of Irrigation Area Composition of Well-irrigation District on Irrigation Water Use Efficiency in China
摘要
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 within ±10%,2% respectively.关键词
