基于博弈论组合赋权模糊物元模型的渭河流域陕西段可持续性评价研究
Sustainability Evaluation of the Shaanxi Section of Weihe River Basin Based on Game Theory and a Weighted Fuzzy Matter Element Model
摘要
Abstract
The Shaanxi section of the Weihe River basin was selected for research,and we evaluated its sustainability,explored evolutionary patterns and identified key factors influencing sustainability.Our aim was to provide a scientific basis for water resource management and high-quality development.Consider-ing the existing situation and development needs in the basin,we selected evaluation indicators related to water security and resources,ecological health,water quality,water economy,and water culture to develop an evaluation system based on relevant data from 2012 to 2021.First,the G1 method and entropy weight method were used for determining the subjective and objective weights of indicators,and the comprehen-sive index weight of each indicator was then determined using a combinatorial weighting method based on game theory.Next,a fuzzy matter-element model was constructed,and finally the improved TOPSIS-RSR-Fuzzy method was used to evaluate watershed sustainability and analyze model sensitivity.Indicator weights for watershed runoff regulation and watershed biological integrity ranked high:the weight for watershed runoff regulation was 0.156 and that for watershed biological integrity was 0.108.The evalua-tion results of the model were consistent with the existing situation.From 2012 to 2014,the river basin was at the preliminary sustainable level,and the evaluation score for sustainability increased steadily from 2015 to 2021,with the highest score of 0.699 in 2021.Analysis showed that the sensitivity of indicators varied by year,and the dike compliance rate,eutrophication rate,and urban flood control compliance rate fluctuated dramatically.Based on our findings,we make the following suggestions:ensure water secu-rity in the basin,rationally manage water resources,promote coordinated development of the economy,culture,and environment,and improve the happiness of residents.These suggestions provide a basis for rational water resource management and sustainable development in the Shaanxi section of Weihe River basin.关键词
