基于公平性的节水型社会评价研究

从公平性角度考虑,构建节水型社会评价指标体系,采用基尼系数-支持向量机耦合评价模型,对东江流域节水型社会进行综合评价,结果表明:东江流域节水公平性级别总体处于Ⅲ类即分布差距较大,并倾向于Ⅱ类即分布相对公平,评价结果比较切合流域实际情况;与层次分析方法相比,该耦合评价模型具有一定的优势。

Research on the Water-saving Society Based on the Equity Principle

This paper introduces the methods of Gini coefficient and support vector machine (SVM), and establishes the equity assessment model of SVM combined with Gini coefficient.Based on the equity principle, with the establishment of a water-saving society, the model of Gini coefficient method combined with SVM is applied to the assessment of a water-saving society in the Dongjiang River Basin. The results show that the equity of water-saving society in Dongjiang River Basin belongs to band Ⅲand inclines to bandⅡ-relative equity of distribution. To a certain extent, the results are based on the realities in the Dongjiang River Basin. Compared with the AHP method, the model of Gini coefficient method coupled with SVM is better.
