基于绿色基础设施的陕南地区小城市开敞空间构建

Open Space System Planning of Small Cities in Southern Shaanxi Region from Green Infrastructure Perspective

针对陕南地区小城市建设用地紧张,开敞空间分布破碎化且总量不足等问题,研究引入绿色基础设施相关理论与方法,对其开敞空间进行系统建构。以商南县城为实践对象,通过评估、提取,从区域层面确定开敞空间的网络中心及廊道,同时利用网络分析的GIS技术平台,对建成区内部开敞空间分布的有效性进行分析,确定开敞空间的规划布局,探索更加适应地域生态环境和城市发展特征的开敞空间规划途径。

Combining with the status quo of small cities in southern Shaanxi,we explore the process and methods of openspace planning under the perspective of GI(Green In frastructure).T h rough dat a colle ction,analysis and evaluation,we determine the hubs and links of open space from the region.Then according to the analysis correlation of open space distribution by using network analysis of GIS,we emphasize the adaptive planning of open space,and we also explore the constructing adaptive planning of open space system,which adapts to the ecological environment and urban development.
