中文摘要: 详细分析了节水灌溉发展水平的影响因素,选取工程节水、农艺节水和管理节水3项2级指标和灌溉水利用系数等33项3级指标,构建了节水灌溉发展水平综合评价指标体系。采用主成分分析法,将以上指标体系在保留原始指标信息的前提下简化为14项主成分因子,以互不相关的较少的综合指标来反映原始指标所提供的信息;采用熵权法确定客观权重,层次分析法确定主观权重,进而得到组合权重;采用集对分析计算联系度得到区域节水灌溉发展水平综合评价结果。以四川省各地区节水灌溉发展现状为例进行计算,评价结果表明:只有成都、攀枝花2个地区处于“一般”水平,占整个地区的9%,处于“较差”和“差”水平的分别有7个地区和12个地区,所占比例为33%、58%;四川全省区域节水灌溉发展水平综合评价结果处于“差”水平。研究结果表明,未来针对不同地区采取合理措施情况下四川省发展节水灌溉的潜力较大。
Abstract:Connotation of water-saving irrigation was elaborated, and the factors of water-efficient irrigation developing were analyzed.Three items of sub-indices of engineering,agriculture and management water-saving were adopted. Firstly, main ingredients with thirty-three indices of the sub-indices were extracted to reduce the number of evaluation indices and establish index system of regional water-saving irrigation developing level evaluation model.Secondly,combination weights were formed from both of objective weight determined by entropy weight method and subjective weight determined by analytic hierarchy process method.Finally,the set pair analysis was selected for analysis.The evaluations showed that two regions are of general,seven regions are of relatively poor,twelve regions are of poor,and the rations of them in all regions are 9%,33% and 58%,respectively.The results indicated that water-efficient irrigation developing level of every region is still lower,and the overall of Sichuan province is evaluated with level of poor.Therefore,the model has a strong practicality to evaluate the water-saving irrigation development in different regions.
