基于模糊层次分析法的水系治理工程效果评价研究

Research on Evaluation of Water System Regulation Engineering Effect Based on Fuzzy Analytic Hierarchy Process

以英德市石灰铺镇农村水系治理工程为研究对象,分析了当地河道、池塘和灌区3个方面存在的问题及相关整治工程。从生态、经济和社会效益3个方面考虑,构建了包含二十项子指标的评价指标体系,并采用模糊数学和层次分析方法建立了适用于评价水系治理工程的模糊层次分析模型。实际应用表明,提出的模糊层次分析方法可以较好地对治理工程进行综合评价,所建立的指标体系具有良好的适用性,指标获取方式简单,评价结果具有良好的参考价值。该工程的综合评价指标为0.70,证明治理工程达到了预期效果。因此,提出的评价方法可以为农村水系治理工程提供技术指导。

This study takes the rural water system regulation engineering in Shihuipu Town,Yingde City as the research object,and analyzes the problems and related remediation projects in three aspects:local rivers,ponds,and irrigation areas.From the perspectives of ecological,economic,and social benefits,an evaluation index system consisting of twenty sub indicators was constructed,and a fuzzy analytic hierarchy process model suitable for evaluating water system regulation engineerings was established using fuzzy mathematics and analytic hierarchy process methods.Practical applications have shown that the proposed fuzzy analytic hierarchy process can effectively comprehensively evaluate regulation engineerings,and the established indicator system has good applicability.The method of obtaining indicators is simple,and the evaluation results have good reference value.The comprehensive evaluation index of this project is 0.70,which proves that the regulation engineering has achieved the expected effect.Therefore,the proposed evaluation method can provide technical guidance for rural water system regulation engineering.
