摘　　要：农业面源污染治理是我国“十四五”重点流域水环境综合治理中的重要组成部分,为了解析鄱阳湖流域农业面源污染特征与时空分布情况,推进区域内农业面源污染治理工作的落实开展,以鄱阳湖流域南昌湖区为研究对象,通过资料收集、实地考察以及数据分析等方法,系统地统计了2020年度鄱阳湖流域南昌湖区五大国控断面汇水区域内的农村生活污水、农业种植、畜禽养殖、水产养殖四大农业面源污染产生的入湖污染负荷,分析了南昌湖区不同农业面源类型污染特征以及入湖污染物的空间分布情况。结果表明:农村生活污水污染主要集中在青岚湖、金溪咀刘家和伍湖分场3个国控断面汇水区域,农业种植面源污染主要集中于青岚湖国控断面汇水区域,畜禽养殖污染绝大部分集中在青岚湖、金溪咀刘家国控断面汇水区域,水产养殖污染主要集中在金溪咀刘家、南矶山国控断面汇水区域;其中青岚湖和金溪咀刘家区域内的农业面源污染是南昌湖区亟需治理的重点,COD、NH_(4)^(+)-N、TN、TP产生量分别占据5个国控断面农业面源污染总量的78.6%、66.7%、70.9%和69.0%。Agricultural non-point source pollution control is an important part of the water environment treatment of key river basins during the 14th Five-Year Plan period.In order to analyze the characteristics and temporal-spatial distribution of agricultural non-point source pollution in Poyang Lake basin,this paper takes Nanchang Lake District of Poyang Lake Basin as the research object.To promote the implementation of agricultural non-point source pollution control in the region,the pollution load of the four agricultural non-point sources of rural domestic sewage,agricultural planting,livestock and poultry breeding and aquaculture in the catchment area of Nanchang Lake area in Poyang Lake Basin in 2020 was systematically analyzed through field investigation,data collection and analysis.Results show that:The pollution of rural domestic sewage is mainly concentrated in the catchment area of Qinglan Lake,Jinxi Tsui Liujia and Wuhu Branch,the non-point source pollution of agricultural planting is mainly concentrated in the catchment area of Qinglan Lake,Jinxi Tsui Liujia state-controlled section,and the pollution of livestock and poultry breeding is mostly concentrated in the catchment area of Qinglan Lake and Jinxi Tsui Liujia state-controlled section.The pollution of aquaculture mainly concentrated in the catchment area of Liujia and Nanjishan state-controlled section in Jinxi Tsui.Among them,the agricultural non-point source pollution in Qinglan Lake and Liujia area in Jinxi is the key point that needs to be controlled in Nanchang Lake District,and the production of COD,NH_(4)^(+)-N,TN and TP account for 78.6%,66.7%,70.9%and 69.0%of the total agricultural non-point source pollution in the five state-controlled sections,respectively.
