摘要
长江口是长江入海口和上海市重要的水源供应地。该研究根据长江口2021年4月份的水文水质监测数据,利用灰色聚类分析法对调查的长江口南、北支和东滩湿地12个站位涨落潮时的水环境状况进行评价,以期了解上海市长江口水域的水环境质量。结果表明:(1)涨潮期间,Z1、Z3、Z5、Z6、Z7、Z9、Z13、Z14、Z16、Z18、Z19等11个站位点的海水水质质量等级为Ⅲ类,东滩的Z17站点为Ⅱ类海水;(2)落潮期间,Z1、Z3、Z6、Z7、Z9、Z13、Z14、Z16、Z17、Z18、Z19等11个站点海水水质质量等级为Ⅲ类,北支Z5站点为Ⅱ类海水。通过利用灰色白化权函数对长江口各站点水质进行分析,长江口属于第Ⅲ类海水,污染情况仍处于比较严重水平。
The Yangtze Estuary is an important water source for Shanghai.Based on the hydrological and water quality monitoring data of the Yangtze Estuary in April 2021,this study evaluated the water environment status of 12 stations selected from the investigation on the north,south branches and Dongtan of the Yangtze Estuary by using grey cluster analysis method,so as to analyze the water environment quality of the Waters of the Yangtze Estuary in Shanghai.The results show that the sea water quality at Z1,Z3,Z5,Z6,Z7,Z9,Z13,Z14,Z16,Z18 and Z19 stations is class ⅲ,and that at Z17 station is class ⅱ.The sea water quality of Z1,Z3,Z6,Z7,Z9,Z13,Z14,Z16,Z17,Z18and Z19 stations is class ⅲ,and that of Z5 station is class ⅱ.It can be seen from the water quality analysis results of the above stations that the water quality of the Yangtze River estuary mostly belongs to class ⅲ seawater,and the water quality is still at a poor level.
