[Objective] The overall scheme of soil and water conservation for plain river district was put forward to refine the regulation scheme of soil and water conservation. [Methods] Using numerical models, we analyzed the features of soil and water loss of Shanghai City qualitatively and quantitatively by studying the situations of soil and water conservation and found out the problems needed to be corrected in similar district. [Results] In terms of soil and water conservation, Shanghai City could be sub-zoned into key prevention sub-areas(ten units in four parts), key control sub-areas(including main waterways and stream channels with quick current ), and erodible sub-areas(including key prevention sections, key control sections and developing and constructing sections). Beside that, some suggestions on how to reinforce the conservation regulation and some regulation works needed to be carried out in the future were proposed. [Conclusion] Policy of ecological civilization promotion in Shanghai City should be conducted well to improve the municipal management of soil and water conservation.
