基于FAHP法的宁夏现代化生态灌区健康评价体系研究与实证

A Health Evaluation System for Modern Ecological Irrigation Districts in Ningxia Based on FAHP Analysis Research&Empirical Evidence

为对现代化生态灌区建设情况进行科学合理的评价,针对指标选取中存在的随意性、重复性和不完整的问题,基于模糊层次分析法,结合国内大型灌区现代化建设内容与目标,从安全保障与服务能力现代化、工程设施现代化、创新能力现代化、管理体制现代化、节水高效与生产效益、生态环境优良化等6个方面构建了宁夏现代化生态灌区健康评价体系,采用指标优选模型,将评价指标由44项优化减少至27项,表达了90.37%的整体体系内涵,满足了指标数量少、完整性高的目标。并以宁夏现代化生态灌区试点县为评价对象,对评价体系进行了实证研究,结果表明利通区57.85%属于健康水平,与灌区实际情况相吻合,评价体系能基本反映试点县在推进现代化生态灌区建设进程中的主要成效及存在问题,也表明现代化灌区评价指标体系与评价方法可行、合理。

To make a scientific and rigorous assessment of the construction of modern ecological irrigation districts,this paper based on fuzzy analytic hierarchy process to address the issues of randomness,repeatability,and incompleteness in indicator selection.Focusing on objectives of large-scale irrigation district modernization in China,a comprehensive evaluation system for the health of the modern ecological irrigation district in Ningxia was developed.The evaluation system comprised six aspects,including modernization of safety assurance and service capacity,modernization of engineering facilities,modernization of innovation capabilities,modernization of management systems,water-saving efficiency and production efficiency,and optimization of the ecological environment.By applying an index optimization model,the number of evaluation indicators was reduced from 44 to 27,capturing approximately 90.37%of the overall system’s essence.This optimization achieved the desired outcome of fewer indicators while maintaining a high level of comprehensiveness.Taking the pilot counties of Ningxia modern ecological irrigation district as the evaluation object,an empirical study of the evaluation system was conducted.The results showed that 57.85%of Litong District was at a healthy level,which was consistent with the actual situation of the irrigation district.The evaluation system could effectively reflect the main achievements,existing challenges,and deficiencies of the pilot counties’efforts to promote the construction of a modern ecological irrigation district.The study also illustrates the feasibility and soundness of the evaluation index system and evaluation method to modern irrigation districts.
