摘要
通过构建包括节水技术投入在内的农业用水评价指标体系,采用熵权法,结合模糊物元法对原始数据进行处理,并在此基础上引入欧氏贴近度,得到各年份农业用水效率的综合评价以及优劣次序。对江苏省历年农业用水效率评价结果表明,基于熵权的模糊物元法能更加客观地确定权重,其评价结果具有一定合理性。研究结果及相关建议有助于江苏省由"用水大户"向"节水大户"转型。
By constructing an agricultural water evaluation index system, including water-saving technology inputs, the information entropy method is used to determine the weights of the evaluation indexes, and the raw data is processed in combination with the fuzzy matter-element method. On this basis, Euclidean closeness is introduced to obtain comprehensive evaluation and ranking of the efficiency of agricultural water use in each year. The evaluation results of Jiangsu＇s agricultural water use efficiency over the years show that the fuzzy matter-element method based on entropy weight can determine the weight more objectively, and its evaluation result has certain rationality. The results of the study and relevant suggestions will help Jiangsu Province to transform from a ＂large water user＂ to a ＂large water-saving province＂.
