| 摘 要： | 基于集对分析原理提出了生态环境质量评价新方法--集对分析法,考虑了分级标准的模糊性,同时避免了差异不确定系数的取值.应用于我国各省市生态环境质量的评价,并与EQI法、PPDC法进行对比.结果表明,该法概念清晰、结构简单、计算简洁、易于操作、可行有效.

| Abstract: | A new approach of ecological environment level evaluation,Set Pair Analysis Method,has been proposed in this paper.The proposed method can take fuzzy property of threshold values for grade standards into full account and avoid determining the discrepancy uncertainty coefficient.A case study of the nationwide ecological environment level evaluation has been researched.The comparison of proposed method with EQI and PPDC has been performed.The results have shown that the proposed method is simple in concept,co... |
