%X Based on the analysis of the framework and calculation principles of Citygreen model in assessing the benefits of urban greenbelt in carbon fixation and runoff reduction, an approach was made to obtain appropriate parameters of this model to calculate the ecological benefits of different urban land use types in the main urban district of Nanjing. The results indicated that the main urban district of Nanjing had much lower carbon fixation benefit than natural forest on per unit area base, being about 5%-60% of the latter. The ecological value of carbon fixation and runoff reduction of Nanjing urban greenbelt was about 177 million RMB in total, and the ecological benefits of different land use types were in the order of green land>public facility>residential>road and square>industrial>municipal. This research could provide references for city planning and urban greenbelt establishment, and facilitate the popularization of quantitative assessment on greenbelt ecological benefits of Chinese cities.
