中文摘要:
      流域水污染负荷估算及污染源解析是流域水环境治理的基础性工作。本文采用监测和统计数据,综合考虑点源和非点源污染,估算2016年御河流域水污染负荷。在地理信息系统支持下,基于流域数字高程模型和监测断面位置将流域划分为6个控制单元,提出了入河系数的估算方法,分析了各控制单元各类污染源的贡献。结果表明:2016年COD、NH3-N和TP入河量分别为7 297.38 t/a、1 163.31 t/a和124.39 t/a,其中分别有70.06%、86.47%和68.04%来源于点源污染。污染物主要来自十里河上游和御河上游,未收集的点源是御河最主要的污染源,对COD、NH3-N和TP贡献率分别达到44%、79%和52%。研究结果对山西省御河流域水环境治理提供了科学依据。
英文摘要:
      Pollution load estimation and source analysis are fundamental tasks of water environment management. Based on monitoring and statistical data, considering point source and non-point source pollution, water pollution loads and main pollution sources were analyzed in the Yuhe basin, Shanxi Province of 2016. Considering the digital elevation model and positions of monitoring station, the river basin was divided into six control districts with support of Geographical Information System (GIS), an estimating method of pollution loss is proposed to calculate the pollution load from different pollution sources. The results showed that in 2016, 7 297.38 tons of COD, 1 163.31 tons of NH3-N, and 124.39 tons of TP were discharged into the Yuhe Basin, of which 70.06%, 85.47% and 68.04% were from point source pollution. The spatial analysis indicated that pollutants mainly came from the upstream of the Shili River and the Yuhe River, andwas mainly ascribed to uncollected point source pollution, and contribution rates of COD, NH3-N and TP were 46%, 80% and 49%, respectively. The results provided a scientific basis for water environment management in the Yuhe Basin.
