摘要
通过同步监测2010年-2013年入湖监测断面水质和水量,分别计算了丰水期、平水期和枯水期以及全年入湖污染物通量。结果表明,2010年-2013年,入湖10个断面水质达标率在80%~100%之间,化学需氧量均是进入鄱阳湖的主要污染物。各污染物主要通过赣江主支、赣江中支、赣江南支、赣江北支、信江西支和饶河6条河流进入鄱阳湖;氨氮浓度年均值与水量相关性均呈负相关,而化学需氧量、总磷和总氮浓度年均值与水量无明显相关性。
In order to understand the main pollutant fluxes into Poyang Lake, water quality and water quantity are monitored in 2013 -2013, and the main pollutant fluxes are calculated under high water season, normal water season, and dry water season. Results show that the pollutant flux is more in high water season than in normal water season, while the pollutant flux is more in normal water season than under dry season. The pollutants are discharged into Poyang Lake by the main branch, west braneh and north branch of Gangjiang, the west branch of Xinjiang, and Raohe. There is a significant negative correlation between the water quantity and the annual average concentration of ammonia nitrogen, while the annual average concentrations of COD, TP, and TN have no significant correlation with water quantity.
