解析当代大都市区绿带规划、建设与治理--以上海环城绿带为例

Analysis of Greenbelt Planning,Construction and Governance in Contemporary Metropolitan Areas:A Case Study of Shanghai Greenbelts Around Metropolis

1990年以后,大都市区绿带规划由限制城市蔓延的现代主义规划策略逐渐转变为能够促进地区发展的政治治理手段。首先梳理了国际绿带规划范式演进趋势和影响绿带规划的关键因素,其次回顾了上海环城绿带的规划思路、建设机制和治理路径,并以上海宝山区顾村公园绿带为对象进一步分析了上海环城绿带由城市空间的结构性要素向区域功能性要素转变的过程,最后对上海环城绿带的规划转型提出了几点建议。上海环城绿带曾肩负着控制城市蔓延的阶段性使命,现在主要承载培育周边土地价值、服务社区居民和提高整个城市吸引力的任务。未来,上海需:1)建设更多具有互通功能的楔形绿地;2)为新规划的绿带制定更为详细的控制性规划;3)将绿带与周边土地整合起来用于培育土地价值和孵化创新产业发展。

Since 1990,the metropolitan greenbelt planning has gradually changed from the modernist planning strategy that limits urban expansion to the political governance measures to promote regional development.This research firstly reviews the paradigm evolution of international greenbelt planning with analysis of the key factors affecting greenbelt planning.Secondly,it reviews the planning ideas,construction mechanisms and governance paths of Shanghai greenbelts around the metropolis.Citing the Gucun Park greenbelt in Shanghai Baoshan District as an example,analyzes the changing process of Shanghai greenbelts which has transformed from urban spatial structural elements to regional functional elements.Finally,this research puts forward some suggestions for the future greenbelt planning in Shanghai.In history,Shanghai greenbelts took the role of controlling urban expansion.Now,they shoulder the mission of cultivating the value of surrounding land,serving the community residents and making the city more attractive.In the future,Shanghai should 1)build more green wedge-shaped green spaces with the interconnected function,2)develop more detailed plans for the newly planned greenbelts,and 3)integrate the greenbelts with surrounding land to cultivate land value and incubate innovative industries.
