| 摘 要： | 针对以往节水灌溉综合效益评价中多采用简单的多指标综合评价的不足,运用熵权法来确定评价指标的权重,建立基于熵权的物元可拓模型对灌区节水灌溉综合效益进行评价,分别从节水灌溉的社会效益、经济效益和生态效益3个方面入手,构建评价指标综合体系.并以吉安市的田南灌区、谷口灌区、银湾桥灌区和南车灌区共4个灌区为实例进行评价,结果显示:银湾桥灌区的节水灌溉综合效益级别为“一般”,田南灌区的节水灌溉综合效益级别向“一般”级别转化,谷口灌区的节水灌溉综合效益级别向“较好”级别转化,而南车灌区的节水灌溉综合效益级别向“好”级别转化,采用灵敏度分析方法进一步验证评价结果的稳定,所得评价结果科学可靠.说明熵权物元分析法在节水灌溉综合效益评价中具有一定的应用价值.

| Abstract: | In view of shortcomings in multiple simple index comprehensive evaluation methods in comprehensive benefit evaluation of water saving irrigation in the past, an entropy weight method is used to determine weight of each evaluation index, and a matter element extension model based on the entropy weights is established to evaluate the comprehensive benefits of water saving irrigation in irrigation districts. An evaluation index system is developed by taking three aspects such as social, economic and ecological benefits into consideration. Four irrigation districts in Ji'an are evaluated with the above method and models. The results show that the comprehensive benefit level is fair in the Yinwan Bridge irrigation district, but the benefit levels are becoming fair, good and fine in the Tiannan, Guko and Nanche irrigation district, respectively. The stability of the results is verified by sensitivity analysis method. The study shows that the entropy weight analysis method has a certain application significance in the comprehensive benefit evaluation of water saving irrigation. |
