摘要：
水质评价是保护和开发利用水资源的一项基本工作.为了系统评价保山市东河污染情况,明确主要污染物和污染来源,基于2020年新东河流域水质监测数据,采用时序全局主成分分析(GPCA)和加拿大环境部长理事会水质指数(CCME-WQI),分析东河干流水质参数的时空变化,发现东河主要污染物为总氮、五日生化需氧量和总磷,主成分综合得分结果显示6、7月污染水平高,8、9月污染水平低.CCME-WQI得分显示新东河流域整体水质较差,污染程度由重到轻为中部、东南部、北部,主要污染来源于城镇、农村生活源、化肥、工业源和分散式禽畜养殖污染源,此研究可为保山市东河水环境污染治理和改善提供理论依据.
Water quality assessment is a basic work for the protection,development and utilization of water resources.In order to systematically evaluate the pollution of the Donghe River in Baoshan City and identify the main pollutants and pollution sources,this study analyzed the temporal and spatial variation of the water quality parameters of the main stream in Donghe River by using time series global principal component analysis(GPCA)and Canadian Conference of Ministers of the Environment Water Quality Index(CCME-WQI)based on the water quality monitoring data of the New Donghe River basin in 2020.The results show that the main pollutants in the Donghe River were total nitrogen,five-day biochemical oxygen demand and total phosphorus.The results of principal component comprehensive score show that the pollution level was high in June and July and low in August and September.The CCME-WQI results show that the overall water quality in the New Donghe River basin was poor,and the degree of pollution ranged from heavy to light in the order of central,southeastern and northern.The pollutants mainly come from urban and rural living sources,chemical fertilizers,industrial sources,and distributed livestock breeding pollution sources.This study can provide a theoretical basis for the treatment and improvement of water environment pollution of Donghe River in Baoshan City.
