摘要
汾河作为山西最大的河流,是山西饮用水及农业用水的主要来源。本文以汾河监测断面水质为评价对象,选取化学需氧量、石油类、氨氮、挥发酚、氰化物、氟化物、铅和镉8个评价因子,基于MATLAB和SPSS软件,采用熵权-TOPSIS法对汾河检测断面进行水质评价,并对比了主成分分析法和灰色关联分析法。研究结果表明,基于熵权-TOPSIS法的汾河水质评价方法切实可行,为监测和治理汾河水质状况提供了合理可靠的依据。
As the largest river in Shanxi,Fenhe River is the main source of drinking water and agricultural water.In this paper,the water quality of Fenhe monitoring section is taken as the evaluation object,and eight evaluation factors,such as chemical oxygen demand,petroleum,ammonia nitrogen,volatile phenol,cyanide,fluoride,lead and cadmium,are selected.Based on MATLAB and SPSS software,EW-TOPSIS method is used to evaluate the water quality of Fenhe monitoring section,and principal component analysis and grey relational analysis are compared.The results show that the evaluation of Fenhe River water quality based on EW-TOPSIS method is feasible,which provides a reasonable and reliable basis for monitoring and controlling Fenhe River water quality.
