摘要
为探寻上海市徐汇区水质常规指标与底栖动物指数之间的关系,文章从水环境质量和水生态状况两方面入手,综合考察水质情况.文章首先选取典型河道中的8个监测断面,采用水质综合指数、底栖动物指数和灰色关联分析法对水质情况进行评价.灰色关联分析法的评价结果显示,在水质常规指标中,溶解氧和粪大肠菌群对底栖动物指数的影响最大.其次,结合水质常规指标和底栖动物指数开展综合评价,发现水质最好的断面为上澳塘宜山路桥和北潮港凌云路桥.最后,根据研究结果,为上海徐汇区河道加快水生态恢复提供对策和建议.
Abstract
In order to explore the relationship between conventional water quality indexes and zoobenthos index in Xuhui District,Shanghai,the water quality was comprehensively considered from the water environmental quality and the water ecological status.This paper selects eight monitoring sections of typical rivers to evaluate their water qualities by using the comprehensive indexes of water quality,zoobenthos index and grey relational analysis.The results of the grey relational analysis show that the dissolved oxygen and fecal coliforms have the greatest influence on the zoobenthos index among the conventional water quality indicators.The best sections of water quality are Yishan road and bridge in Shang'aotang and Lingyun road and bridge in Beichaogang,based on the comprehensive evaluation of conventional water quality indicators and zoobenthos index.According to the research results,some countermeasures and suggestions are put forward for the restoration of river water ecology in Xuhui District,Shanghai.
