基于博弈论组合赋权的水环境综合治理效果评价

随着人们对水环境要求的提高和政府投资力度的加大，水环境综合整治取得了一定的效果，但目前还没有针对水环境综合整治效果的评价指标体系。从水体改善、景观、生态、功能和社会民生5个方面选取17项指标建立了水环境综合治理效果评价指标体系。基于博弈论均衡和协调的基本思想，利用AHP法确定主观权重，熵法确定客观权重，通过组合赋权得出综合权重，构建了基于博弈论组合赋权的水环境综合治理效果评价模型。结合宣城市2015—2017年水环境综合治理效果的相关数据进行评价，评价结果显示2015年宣城市水环境综合治理效果评价等级为中，2016年和2017年评价等级均为良；综合评价得分呈逐年上升趋势，表明治理效果不断提高。

Evaluation of comprehensive water environment treatment effect based on game theory combination weighting

With the increasing requirement of water environment and the enlargement of government investment, a comprehensive improvement of water environment takes shape to some extent, but no evaluation index system for the comprehensive improvement of water environment is proposed. 17 indexes are selected from aspects of water improvement, landscape, ecology, function and social people's livelihood to establish an evaluation index system. Based on the basic thoughts of game theory equilibrium and coordination, AHP is used to determine the subjective weight and entropic law is applied to confirm the objective weight. The comprehensive weight is thus obtained through the combined empowerment. A comprehensive improvement evaluation model for water environment based on the combined empowerment of game theory is constructed and evaluated by using the relevant data of comprehensive improvement effect for water environment in Xuancheng City in 2015-2017, showing that the comprehensive improvement evaluation grade for water environment in Xuancheng City in 2015 belongs to medium-grade and that of 2016 and 2017 is within high-grade. The comprehensive evaluation on the upgrade, indicates that the improvement effect is constant, and that the evaluation index system provide a basis for evaluating and inspecting the comprehensive improvement of water environment in other cities.
