摘　　要：为丰富水生态承载力研究方法,将加权Bonferroni算子(weighted Bonferroni mean,WBM)应用于水生态承载力评价研究,构建相应的WBM评价模型。通过建立水生态承载力评价指标体系,运用层次分析法和改进熵权法确定指标权重,再利用WBM评价模型进行承载力评价,并将其与广泛应用的TOPSIS模型评价结果进行对比,以太原市为例对方法的可靠性进行验证,进一步采用障碍度模型识别影响水生态承载力的关键障碍因素。结果表明:太原市2009—2020年水生态承载力状态于临界承载上下波动,整体变化趋势不显著,近年来呈良好态势发展;水资源、水生态子系统承载状态波动较大;通过与TOPSIS模型对比,该评价模型评价结果较为一致,表明WBM模型适用于水生态承载力综合评价;制约该地区的障碍因素主要集中在水资源子系统。Water ecological carrying capacity is a comprehensive concept based on the theory of carrying capacity,considering water resources,water environment,and other factors to study the water ecosystem.It is based on the principle of sustainable development,covering water resources and the water environment,emphasizing the sustainable carrying capacity of water ecosystem to human society and economy.At present,the evaluation methods of water ecological carrying capacity mostly referred to the research of water resources carrying capacity and water environment carrying capacity,including SD,fuzzy evaluation method,TOPSIS model,and so on.The Bonferroni mean operator proposed by Bonferroni can effectively capture the correlation between input variables and can aggregate multiple input variables into one input variable.It is an aggregation operator between the maximum and the minimum.This method eliminated the mutual influence and interdependence between variables through iterative operation so that the comprehensive evaluation results can be fair.In recent years,the Bonferroni mean had been well expanded and applied in practical problems such as multi-attribute comprehensive evaluation and group decision-making.Xia et.al introduced the weight vector of the variable into Bonferroni mean and proposed the weighted Bonferroni mean,which considered the relative importance of the variable itself.Try to weaken the influence of the correlation between indicators on the evaluation results of water ecological carrying capacity and enrich the research methods of water ecological carrying capacity,the weighted Bonferroni mean operator was employed in the evaluation system of water ecological carrying capacity,and a comprehensive evaluation model of water ecological carrying capacity-WBM evaluation model was established.Taiyuan City was taken as the research object to verify the reliability of WBM,to provide an alternative method for the evaluation of water ecological carrying capacity,and provide support for promoting regional ecosys
