%X 28 typical wetlands were selected to monitor the contaminants in water monthly, that influenced by urbanization in different scales. On the other hand, the land use types such as impervious area and forest area in the catchments of urban wetlands were analyzed by GIS and landscape ecology. And then the effects of urbanization index (UEI) was employed to reveal the relationship between urbanization level and water quality in Xianlin New City of Nanjing. Results indicated that: 1 the seasonal variations of water quality showed that water quality in summer was worse than those in other seasons, and the water quality in winter was good. However there were no significant differences between the spring and the autumn. 2 the relationship was significant between urbanization level and water quality, and the water quality tended to be getting worse when the urbanization level was getting higher. The concentrations of TP, TN, NH4+-N, and Chla were 0.27, 1.07, 0.15 and 17.94 mg·L-1respectively in the high urbanization(HU) level wetland while the concentrations were 0.12, 0.56, 0.12 and 4.85 mg·L-1 in the low urbanization(LW) level wetland. 3there was a threshold between UEI and the water quality. On the whole, the water quality would get worse quickly when the value of UEI exceeded 2.2.
