| 摘 要： | 综合考虑水环境污染的脆弱性和受污染水体对人体健康的危害性, 建立了河流水环污染风险模糊综合评价模型.运用模糊语言,将脆弱性和危害性均分为6个等级,并根据F统计法和专家咨询法确定脆弱性和危害性的模糊隶属函数.由模糊综合评价得出河流水环境污染的风险水平.将该评价模型应用到湘江14个断面的水环境风险评价中,直观地表达各个断面污染风险水平,为湘江水资源管理和优先控制断面的选取提供新思路和新方法.

| Abstract: | Considering both the vulnerability of water environmental and hazard to human beings,an integrated model for assessing the risk of water environmental pollution was developed based on fuzziness.In this model,vulnerability and hazard were both divided into six categories based on fuzzy theory.The fuzzy membership functions of vulnerability and hazard were built by the experts consultation and F statistical method.In order to obtain general risk of water environmental pollution,integrated evaluation was used ... |
