| 摘 要： | 针对现有环境质量评价指数的不足,提出了一种基于可拓理论的新指数——可拓综合指数(EQI): EQI=sum from j=1 to m j·(?)_j(p)/sum from j=1 to m(?)_j(p)。其中,K_j(p)为待评对象p关于等级j的关联度。构建了基于MS Excel和MATLAB并通过Excellink联系的可拓综合评价系统,主要包括评价标准数据库模块和可拓质量评价模块,有简单关联函数法、层次分析法、特尔菲法3种赋权方法可资选择。应用于流溪河水质评价,所得结果与文献报道和水质实际情况吻合。

| Abstract: | Based on the extension theory,extension quality index(EQI)was proposed and a system consisting of water quality standards database and extension quality evaluation module was built for water comprehensive assessment. Three approaches for weight coefficient determining were provided,including dependent function,analytical hierarchy process and Delphi method.Assessment of Liuxi River in Guangzhou was acted as an example to illustrate the feasibility of EQI,and the results obtained was in good agreement with t... |
