中文摘要:
      为了准确把握海河流域邯郸境内农业非点源污染现状,采用输出系数法、等标污染负荷法、ArcGIS技术和系统聚类法对邯郸各县进行污染估算和系统解析。2019年邯郸市农业非点源污染物化学需氧量(COD)、总氮(TN)、总磷(TP)和氨氮(NH3-N)排放量分别为58 396、6 046、1 348和4 669 t,COD污染物排放量最大。等标污染负荷评价显示总氮和总磷是主要污染物,负荷比分别为29.67%和33.08%。畜禽养殖源和化肥流失源是主要污染来源,负荷比分别为41.97%和38.72%,化肥流失污染是TP主要贡献者,畜禽养殖污染是NH3-N主要贡献者,各污染源对COD和TN的贡献率较为平均。将邯郸市农业非点源污染划分为6种污染类型,确定严格监管区并提出相应治理措施,为未来综合治理提供参考和指导。
英文摘要:
      In order to accurately grasp the current situation of agricultural non-point source pollution in Handan of Haihe River Basin, this paper used the output coefficient method, equal standard pollution load method, and ArcGIS technology and system clustering method to estimate and analyze the pollution of counties of Handan city. In 2019, the chemical oxygen demand (COD), total nitrogen (TN), total phosphorus (TP) and ammonia nitrogen (NH3-N) of pollutants in Handan city were 58396t, 6046t, 1348t and 4669t respectively, and the COD pollutants were the largest. The equivalent pollution load evaluation showed that TN and TP were the main pollutants, and the load ratios were 29.67% and 33.08%, respectively. Livestock and poultry breeding source and fertilizer loss source were the main pollution sources, and the load ratios were 41.97% and 38.72%, respectively. The fertilizer loss pollution was the main contributor to TP while the livestock and poultry breeding pollution was the main contributor to NH3-N, and the contribution rates of each pollution source to COD and TN were relatively average. The agricultural non-point source pollution in Handan city was divided into six pollution types, the strict supervision area was determined, and the corresponding treatment measures were put forward so as to provide a reference and guidance for comprehensive treatment in the future.
