灰色关联分析综合评价法在地表水环境评价中的应用

Application of the Gray Association Analysis Method to the Assessment of the Environment of Surface Water

灰色关联分析是通过断面水质的多个水质浓度因子与水质标准的距离分析,最终说明断面水质隶属于哪一级水。利用水质评价关联分析对区域水环境质量进行评价能客观、直接地反映相应某区域水体环境质量或污染程度。本文采用灰色关联分析综合评价法对韩江赤凤、潮安、南社的水体质量进行评价,取得了良好的效果。

Gray association analysis can be used to detemfine the quality level of the cross section of the water by analyzing the distance between multiple density factors of the cross section of the water and the water quality standard With this method, we can determine the water quality and the contamination level in some region objectively and directly by evaluating the quality of the regional water environment. In this paper, we apply the gray association analysis method to Chifeng, Chaoan and Nanshe of Hanjiang for evaluating their water quality, and have achieved satisfactory results.
