摘要
为更精准地评价城市供水安全,将集对分析法与主客观组合赋权法相结合,建立区域城市供水安全评价模型,即用最小相对信息熵原理确定指标综合权重并耦合到指标联系度中,构建出城市供水安全的组合赋权-集对分析的评价体系,通过五元减法集对势确定城市供水安全等级,并对昆明市 2011～2020 年的供水安全评价划分安全等级.结果表明,2011～2013 年昆明市供水处于安全等级,其中 2011、2012 年更倾向于基本安全等级;2014～2020 年昆明市供水处于非常安全等级但更倾向于安全等级,供水状态相对安全和稳定.所提方法一定程度上解决了城市供水安全评价等级中的不确定性和多指标性问题,为城市供水安全评价提供了一种新思路.
Abstract
In order to evaluate the safety of urban water supply more accurately,combination of set-pair analysis and subjective-objective combination assignment method was used to establish a regional urban water supply safety evaluation model.Using the principle of minimum relative information entropy to determine the comprehensive weights of the indi-cators and coupling into the linkage degree of the indicators,the evaluation system of urban water supply safety based combination weighting and set pair analysis was established.Finally,the urban water supply safety level was determined by the five-variable subtraction set pair potential.Taking Kunming City as an example,the evaluation of its water supply safety from 2011 to 2020 is divided into safety levels.The results show that the Kunming City from 2011 to 2013 is in the safety level,of which 2011 and 2012 are more inclined to the basic safety level;From 2014 to 2020,it is in the very safe level but is more inclined to the safe level,and the state of water supply is relatively safe and stable.This method solves the problem of uncertainty and multi-indicator in the evaluation of urban water supply safety to a certain extent,and pro-vides a new way for evaluation of urban water supply safety.
