【摘要】 为了解决缺资料地区的农村面源污染难以定量模拟和综合评估的问题,将输出系数法(the export coefficient model)和源强系数法(source strength coefficient method)进行联合,建立了一套简单、实用的农村面源(非点源)污染评估方法。结合文献和研究区——濑溪河流域(泸县境内部分)的调查数据提出相应的模型系数,进行研究区的农村面源污染评估,得到研究区主要污染类型、主要污染物、主要污染源、重点治理乡镇以及各镇主要污染源,同时,根据该评估结果提出水污染治理对策建议。结果表明,所提出的方法适用于缺资料地区的农村面源污染评估。更多还原

【Abstract】 In order to resolve the difficulty of the quantitative simulation and integrated assessment of rural non-point sources pollution( RNPSP) in regions with sparse data,a simple and practical RNPSP assessment method was developed by combining the export coefficient model( ECM) and source strength coefficient method( SSCM). The corresponding coefficients were selected based on the analysis of the literatures and field survey data. This method and the coefficients were applied to the RNPSP assessment for the Laixi River basin( the part within the Lu county,Sichuan,China),a region with sparse data for coefficient calibration,and the assessments of the dominant pollution source type,key pollutants and key pollution sources of the study area,key towns for pollution treatment,and key pollution sources for each town were obtained. Finally,reasonable and practical suggestions were proposed for the water pollution treatment according to the assessment results. The results showed that the proposed method can be applied to the RNPSP assessment for the regions with sparse data.更多还原
