ZHANG Hao ,WANG Xiang-rong2 ( 1.Department of Environmental Sciences, East China Normal University, Shanghai 200062, China 2.Department of Environmental Sciences and Engineering, Fudan University, Shanghai 200433, China). China Environmental Science. 2001,21(2) 101104 Abstract Urban green space is an important part of urban ecosystem, possessing negative feedback regulating functions, which to a certain extent brings various ecological functions into play to maintain the balance of urban ecosystem. In respect of the capacity of anti-adversity and reforming environment, significant differences exist in green space, which may result from its discrepancy of three-dimensional ecological characters. In this paper, based on analysis on original ecological effect data from field investigation of green space in Shanghai urban districts, the influence of three- dimensional ecological characters on green space’s ecological functions was discussed.
