摘要
目前城市面源污染负荷监测只是零散的探索,缺少系统性研究,尤其对于基于下垫面监测城市面源污染负荷的研究更少。本文以文献调研为基础,在兼顾数据精度与操作方便性的总体原则下,对基于下垫面的城市面源污染负荷监测技术要点进行研究,包括监测点位布设,监测项目选取,监测频次确定,地表径流量获取方法,总量测算方法等内容,为该方法在城市面源污染负荷监测中的应用和推广提供了技术支撑。根据在试点地区开展的4次降雨监测结果,验证该方法可行。
There was only sporadic study on urban non - point source pollution load monitoring, and the lack of systematic study, and the study on method of urban non - point source pollution load monitoring based on urban underlying surface was less. With literature research methods, consideration to data accuracy and ease of operation, the method of urban non -point source pollution load monitoring based on urban underlying surface was studied. The technologies included sites layout, project selection, frequency determination, surface runoff acquisition and pollution load calculation method. It provided technical support for the method applications and promotion on urban non - point source pollution load monitoring. The four pilot regions rainfall monitoring results showed that the method was feasible.
