Sediments’ physicochemical properties of two urban wetlands in Shanghai, Jiangwan and Dalian Lake, were investigated, including density, sediment moisture content, pH, organic matter, total nitrogen (TN), total phosphorus (TP), available nitrogen, and available phosphorus. Sediment samples were collected and analyzed in April, August and November, 2011. The results show that sediment organic matters, TN and available nitrogen, phosphorus contents in Dalian Lake wetland were higher than those of Jiangwan wetland. Sediment organic matter contents: Dalian Lake wetland (38.96~120.19 g/kg)>Jiangwan wetland (20.74~94.64 g/kg). TN: Dalian Lake wetland (13.25~26.93 g/kg)>Jiangwan wetland (5.73~13.56 g/kg). Available itrogen accounted for the proportion of total nitrogen: Dalian Lake wetland (3.28%)>Jiangwan wetland (1.62%). Available phosphorus accounted for the proportion of total phosphorus: Dalian Lake wetland (3.88%)>Jiangwan wetland (2.57%). The results show that the development of Dalian Lake wetland sediment is more stable than Jiangwan wetland. Therefore, Dalian Lake wetland is more suitable to the local ecosystem recovery and healthy development.
