摘要
为科学评价河长制实施效果,也为河长制的实施效果评价提供一种研究思路。以淮安市为研究对象,从经济、社会、生态、文化、水域管理效果5个维度出发,选取21个指标,构建河长制实施效果评价模型。利用序关系法(G1)确定主观权重,熵权法(EVM)确定客观权重,博弈论组合赋权法求得组合权重,并结合集对分析法(SPA)构建基于G1-EVM-SPA的河长制实施效果评价模型,选取时间维度为2017-2020年,对淮安市全面推行河长制4年来的河长制实施效果及协调发展度进行评价,结果表明:2017年河长制实施效果为中等,2018-2020年实施效果为良好,并呈逐年改善趋势。2017-2020年河长制实施效果协调发展度分别为0、0.501 8、0.484 5、0.497 3。除2017年隶属高度不协调等级之外,2018-2020年的协调发展度等级均隶属临界协调等级,且整体的协调发展度呈逐年改善趋势。
To scientifically evaluate the implementation effect of the river chief system and provide a research idea for the evaluation of the implementation effect of the river chief system,taking Huai’an City as the research object,21 indicators are selected from the perspectives of economic,social,ecological,cultural and watershed management effects to construct an evaluation model of the implementation effects of river chief system. The subjective weights are determined by the sequential relationship method(G1),the objective weights are determined by the entropy weight method(EVM),the combination weights are obtained by the game theory combination assignment method,and the G1-EVM-SPA based evaluation model of the implementation effect of the river length system is constructed by combining the set-pair analysis method(SPA),and the time dimension is selected from 2017 to 2020 to evaluate the effectiveness of the implementation of the river chief system and the degree of coordinated development in Huai’an over the past four years since the full implementation of the river chief system.The results show that the implementation effect of the river chief system in 2017 is moderate,and the implementation effect in 2018-2020 is good,and the trend is improving year by year. The coordination development degree of the implementation effect of the river chief system in2017-2020 is 0,0.501 8,0.484 5,and 0.497 3,respectively. Except for 2017,which is under the highly uncoordinated grade,the coordination development degree grades in 2018-2020 are under the critical coordination grade. The overall coordination development degree is improving year by year.
