| 摘 要： | 在对水质综合评价的诸多方法中,模糊综合评价法以其评价结果合理、更接近客观实际等优点,得到越来越广泛的应用。由于某些指标其单项标准限值数少于水质总体分级,采用传统模糊评价方法计算得到的隶属度与实际情况并不相符。针对此类情况,对隶属函数加以改进,提出改进后的模糊评价方法,并将此方法应用于长江下游贵池河段2005年-2009年间水环境综合评价,与传统方法计算结果相比较,取得了较好的效果。

| Abstract: | Fuzzy comprehensive evaluation is widely applied in water quality assessment because of its advantages of reasonable results and closed to the actual situation,etc.Some individual standard limits of a certain index are less than the overall water quality grade,so the subordinate relations calculated by the traditional fuzzy evaluation method do not match with the fact.In order to solve this problem,this study improved the subordinate function,proposed an improved fuzzy evaluation method based on the traditi... |
