摘要
提出了反演分析法,该方法通过河道水量、污染物均衡分析,点源、面源入河量迭代反演,以及全河段水质水量校验,估算局部河道面源污染;并应用于黄柏河流域东支河流,进而验证该反演分析法。结果表明,基于特征污染物及质量平衡的方法能够有效地确定特征点源、面源污染对河道水质的污染贡献,采用特征污染物反演法能够准确估计区域面源污染入河量。
An inversion analysis method was developed to estimate agricultural non-point source pollution emissions, in which agricultural non-point source pollution emissions were estimated through the equilibrium analysis of water and contaminants, iterative inversion calculation of the export load of point and nonpoint source pollutions, and verification of water quality and water amount. The method was tested in the Huangbohe river basin, and was compared with measured concentrations. Results showed that the method, based on representative pollutants and mass balance, could effectively determine the contribution of point and nonpoint pollution to water quality, and the inversion formula could estimate the export load of regional nonpoint source pollution accurately.
