摘要：
This study develops and applies a distributed urban runoff pollution model to the north Moshui lake area of Wuhan for evaluating its non-point source pollution. Based on the research of the urban land utilization and land surface features using GIS, the characteristics of runoff flow, solid suspend (SS) and chemical oxygen demand (COD) on the inlets have been analyzed according the model, the initial pollution loads and the total pollution loads are computed in this study. The results show that the peak of pollutant concentrations are lagged with the peak of rainfall; and the pollutants in initial rainwater are the key part of all pollutants, which often account for 90% proportion. © 2011 Springer-Verlag Berlin Heidelberg.
