| 摘 要： | 在灰色关联理论的基础上,提出了基于超标比与均方差组合赋权的水质综合评价方法,可有效的识别水体中的主要污染来源.通过改进数据标准化的方法,合理的减弱了水质监测数据中的奇点对评价结果的影响.将方法应用于白洋淀五个监测断面的水质综合评价,取得了合理的结果,表明方法可行.

Water Quality Assessment with Grey Correlation Analysis based on Combination Weight |
| |
| Abstract: | Based on grey correlation theory,an improved water quality comprehensive assessment method was proposed by using combination weight with excessive ratio and mean square error,which can effectively identify the main sources of pollution in water.And by improving the method of data standardization,the impact on evaluation results from the singularity of water quality monitorting data was weakened.The study applied this method to the water quality assessment of the five sectiongs of BaiYangDian.The results were reasonable,which proved that the method is feasible. |
