Abstract: This paper analyzed the characteristics of urban watershed in tidal plains. Non-point source pollution management oriented urban watershed division method in tidal plain was proposed from three aspects of spatial scale, runoff mechanism and management intensity. Lingang watershed of Shanghai in China was taken as a case. The results showed that Lingang watershed can be divided into one first-class sub-watershed, 13 second-class sub-watersheds and 137 third-class sub-watersheds. The spatial distribution of the second-class sub-watersheds and function divisions are almost the same, which indicates the proposed method is operable.

Key words: non-point sources (NPS), watershed division, tidal plain, Lingang New City
