海沧湖水质状况评价及水质提升建议

Evaluation of Water Quality of Haicang Lake and Recommendation of Water Quality Improvement

根据2017—2021年海沧湖湖区内9个监测点位的监测数据,分析了监测点位、年际变化、季节变化对海沧湖各水质指标的影响,并且使用单因子污染指数法和内梅罗污染指数法对海沧湖水质进行评价。监测数据显示,2017—2021年海沧湖整体及各监测点位污染物质量浓度呈现总体下降的趋势,冬季污染物质量浓度要低于夏季,单因子污染指数法和内梅罗污染指数法2种方式评价结果均显示2021年海沧湖水质比前4年有明显提升。

According to the monitoring data of 9 monitoring points in Haicang Lake from 2017 to 2021,the influences of monitoring points,interannual variation and seasonal variation on each monitoring index were analyzed.And the water quality of Haicang Lake were evaluated by single factor pollution index method and Nemerow pollution index method.Monitoring data show that the pollutant concentration of Haicang Lake showed an overall trend of decline at each point from 2017 to 2021.The pollutant concentration in winter was lower than that in summer.Both the evaluation results by single factor pollution index method and Nemerow pollution index method show that the water quality of Haicang Lake in 2021 was significantly improved compared with the previous four years.
