15 urban wetlands in Nanjing City were collected to be studied for their vegetation and water quality monthly from March 2008 to February 2009.Further more, the variation of the water quality among 15 urban wetlands was revealed at two scales, i.e, urban wetland ecosystem scale and the catchment scale. Results showed that, (1) the wetland styles including protosomatic wetlands (PWs), secondary wetlands (SWs) and reconstructive wetlands (RWs), together with plant coverage density impacted the water quality obviously at the ecosystem scale. Water qualities in PWs were better than those in SWs and RWs, and the more plant coverage, the better the water quality was. (2) Land use types and impervious areas were the important factors influenced on the water quality at the catchment scale. Resident land and other construct land made the water quality bad at the catchment scale. Key words-urban wetlands; multi-scales; water quality; Nanjing City.
