摘　　要：本文分析了2006—2011年重庆主城区的城市绿地演变,评估了绿地规划实施效果及其对城市空间扩展的约束作用。研究发现:重庆独特的山水格局及其山体绿线控制政策奠定了其多中心组团式的城市空间结构;城市建设不断侵占原有绿地尤其是组团隔离绿地,致使原有绿地不断破碎化和孤立化,降低了绿地规划的约束作用;城郊公园和广场绿地有所增加,这些绿地主要是由农用地转换而来。本文揭示了快速城市化发展与绿地规划管制之间的深刻矛盾,对城市绿地保护和空间格局优化有参考价值。This paper analyzed the evolution of urban green space in Chongqing central area from 2006 to 2011.The effects and constraints of green space planning on urban expansion were further discussed.The results showed that the preservation of vegetated mountainous and hilly areas resulted in polycentric urban structure in Chongqing,which was regarded as one of promising urban forms.However,a large amount of green space was encroached by modern urban development.This development led to fragmentation and isolation of existing green space,thereby imposing constant challenges on green space planning.Fortunately,some green parks and squares newly increased in the suburbs,which were largely converted from agricultural land.The inherent contradiction between urban development and green space protections called for in-depth researches during mountainous settlement development.
