摘 要:为研究红枫湖流域主要入湖污染物情况,采用现场调查、资料收集等方法计算红枫湖流域主要入湖污染物,并分析各污染物的各类型污染源贡献率、各支流贡献率、内源和外源比值等情况。结果表明:在各种降水情景下,入湖的各污染物总量大小顺序均为COD>总氮>氨氮>总磷;各污染物(COD、氨氮、总磷、总氮)入湖量贡献率均是羊昌河最大、麦包河最小,其贡献率范围分别为46.33%~76.6%和0.4%~0.6%;入湖主要污染物(COD、总氮、总磷)主要以外源为主,氨氮则以内源污染为主;研究为红枫湖水环境质量改善、治理方向提供技术支撑。In order to study the main pollutants entering the lake in the Hongfeng Lake Basin,the main pollutants into the lake in the Hongfeng Lake Basin were calculated through field investigation,data collection and other methods. The contribution rate of all type of pollution sources,the contribution rate of each tributary,the ratio of external and internal of each pollutant were analyzed. The results show that the total quantity and size of the pollutants into the lake are all in the order of COD TN NH3-N TP under a variety of precipitation scenarios. The amount of pollutants( COD, TN, NH3-Nand TP) into the lake is contributed by Yang chang river most,and Mai bao river least,the contribution rate of Yang chang river and Mai bao river were46. 33% - 76. 6%,and 0. 4% - 0. 6%,respectively. The main pollutants( COD,TN,NH3-Nand TP) in the lake are mainly from external source,while ammonia nitrogen is the main from internal pollution. This study provides technical support for the improvement and control direction of the water environment in Hongfeng Lake.
