公园城市视角下的城绿融合研究--以南京市明城墙为例

Research on Urban-Natural Integration from the Perspective of Park City:Take Nanjing Ming City Wall as an Example

在工业化不断推进城市发展的同时,人居环境却愈加恶化。如何在维护城市运转的同时创造宜居的城市环境一直受到学界的重点关注。梳理自工业革命以来城市空间与公共绿地关系的历史演变过程,剖析不同历史时期城市空间与自然环境相互融合的时代特征,廓清在新时代公园城市建设背景下城绿融合的时代责任。城绿融合须首先着眼于区域的生态格局,促进城市系统与自然生态系统之间相互融合并能和谐运转;其次强调微观尺度的环境改善,将景观作为载体介入城市结构,塑造城市空间;另外还须注重服务对象与城市治理的公共性及景观设施的人本性,推动规划及治理体系的革新。最后以南京明城墙绿地空间为研究对象,对其在以公园城市为背景下与南京城城市系统之间的融合策略进行探讨。

While industrialization continues to promote urban development,the human settlement environment is getting worse.How to create a suitable living environment while maintaining the operation of the city has always been the focus of the academic circle.This article sorts out the historical evolution of the relationship between urban space and public green space since the Industrial Revolution,and analyze the era characteristics of the integration of urban space and natural environment in different historical periods,to clarify the responsibilities of the era of urban-natural integration in the context of the construction of park cities in the new era.The study concludes that the urban-natural integration must first focus on the regional ecological pattern,promote the integration and harmonious operation of the urban system and the natural ecosystem;secondly,emphasize the improvement of the micro-scale environment,and use the landscape as a carrier to intervene in the urban structure to shape the urban space;In addition,it is necessary to pay attention to the publicity of service objects and urban governance and the human nature of landscape facilities,and promote the innovation of planning and governance system.Taking the green space of Nanjing Ming City Wall as the research object,it discusses its integration strategy with Nanjing city system under the background of park city.
