摘要： 采用排污系数法估算长临河镇3个小流域种植业、畜禽养殖业、水产养殖业和农村生活污染物排放量，用等标污染负荷法进行污染评价，结合水质监测结果深入分析面源污染情况。结果表明：2021年长临河镇3个小流域COD（化学需氧量）、TN（总氮）和TP（总磷）的排放量分别为294.99、56.41和6.41 t，COD排放量最多；种植业等标污染负荷最大，占等标污染负荷总量的44.18%，其次为农村生活源，占比37.59%；TN等标污染负荷量占等标污染负荷总量的54.65%,高于TP和COD；长临河流域的罗店、罗洪、东光和长临社区等标污染负荷量较大, 其等标污染负荷比之和为62.75%。种植业为长临河镇首要污染源，未来长临河镇农业面源污染防控以种植业为主，主要防控污染物为TN，重点控制区为长临河流域。

Abstract: The emission coefficient method was adopted to estimate the pollutant emissions in planting, livestock breeding, aquaculture industry and rural life of three small watersheds in Changlinhe Town. The pollution evaluation was carried out by equivalent pollution load method, combined with water quality monitoring results in-depth analysis of agricultural non-point source pollution. The results showed that the chemical oxygen demand (COD), total nitrogen (TN) and total phosphorus (TP) emissions in Changlinhe Town were 294.99, 56.41 and 6.41 t in 2021, respectively, and the COD emissions were the highest. The equivalent pollution load of the planting was the highest, accounting for 44.18% of the total emission standard, followed by rural life sources, accounting for 37.59%. The equivalent pollution load of TN accounted for 54.65% of the total emission standard, higher than that of TP and COD. Luodian, Luohong, Dongguang and Changlin community had a large equivalent pollution load, and the sum of the equal standard pollution load ratio of these four communities was 62.75%. Agricultural non-point source pollution was dominated by planting industry, in the future, pollution prevention and control should focus on planting industry and the main pollutant of TN should be controlled particularly, and the key control area is the Changlin River Basin.

Key words: agricultural non-point source pollution, emission coefficient method, sources analysis, evaluation, equivalent pollution load method
