基于输出系数模型的琼江流域(安居段)农村非点源污染负荷评估
|
摘要
以琼江流域(安居段)为研究区,采用输出系数模型对研究区内非点源污染负荷量进行估算,并评估了研究区内蟠龙河等4条子流域的污染情况,以期为河长制"一河一策"方案编制提供参考依据。研究表明:2016年研究区农村非点源TN、TP输出负荷量分别为3 319.98,220.5 t,TN负荷主要来源于农业面源,贡献率为54.41%;TP负荷主要来源于农村生活和畜禽养殖污染源,二者总贡献率达74.37%。4个子流域中,蟠龙河流域、石洞河流域主要污染源为农业面源和农村生活污染,玉丰河流域和会龙河流域主要污染源为畜禽养殖和农业面源污染。
In order to provide a reference for the compilation of the "One River, One Policy" for rivers in Anju District, the basin's non-point source pollution load has been calculated by the export coefficient model, and the pollution in four sub-watersheds(Panlong River etc.) was also evaluated separately. The research result showed that, in 2016, the total nitrogen(TN)and total phosphorus(TP)loads of the research area were 3319.98, 220.5 t, respectively. The main pollution source of TN load was agricultural non-point source, with a contribution rate of 54.41%, while the main pollution source of TP load was rural life and livestock and poultry breeding, with a total contribution rate of 74.37%. In terms of the four sub-basins, the main pollution sources in Panlong River Basin and Shidong River Basin were agricultural non-point sources and rural areas, while the main pollution sources in Yufeng River Basin and Huilong River Basin were livestock breeding and agricultural non-point sources.
