Monitoring and Evaluation of Water Quality of Sanggou Bay and Surrounding Waters in Weihai City

摘要:

为研究威海市桑沟湾及周边海域水质情况，本文基于桑沟湾及邻近海域30个站位共采集了100个海水样品，分析了研究区海水水质特征，并结合海洋功能区划，采用了单因子标准指数法和综合指数法对研究区海水水质状况做出了评价。研究结果表明：在100个海水样品中，海水良好级水样共有11件，占总数的11％；较好级水样共有89件，占总数的89％，总体上研究区域海水水质满足各功能区要求，适宜水产养殖活动，具备在此海域建设人工鱼礁的水质环境。

Abstract:

Based on a total of 100 seawater samples from 30 stations in Sanggou Bay and surrounding waters in Rongcheng city, characteristics of seawater quality in the study area have been analyzed.combining with marine functional zoning. The seawater quality in the study area has been evaluated by using single factor evaluation method and comprehensive evaluation method. It is showed that among the 100 samples, there are 11 good grade seawater samples, accounting for 11% of the total, while 89 are less good grade water samples, and accounting for 89% of the total. The seawater quality in the survey area generally meets the requirements of each functional domain.
