As the climate changes, green spaces of all types will be increasingly important in maintaining livable and biodiverse communities. A type of green space common to suburban communities in the United States is residential open space. Residential open spaces tend to be small and heavily managed and are frequently undervalued and understudied as ecological amenities. This study uses GIS analysis and spatial statistics to explore the configuration of 1900 residential open spaces in Montgomery County, Pennsylvania, a suburban county in the northeastern United States. It examines local characteristics such as open space policy, subdivision features, and socioeconomic status to identify variables that are associated with open space parcel size and connectivity and could be leveraged to foster a more beneficial configuration of metropolitan green space. The analysis finds that open space is moderately fragmented, but is abundant in the county and clustered, which could support functional connectivity. Direct connections also considerably augment the size of open spaces and other types of protected greenspaces. Results highlight that municipal actions like setting open space standards, using open space to protect riparian areas, and taking ownership of open space parcels are associated with beneficial on-the-ground open space characteristics.

住宅开放空间在郊区绿色空间网络中的作用和潜力

随着气候的变化,各种类型的绿色空间对于维持宜居和生物多样化的社区将越来越重要。美国郊区社区共有的一种绿色空间是住宅开放空间。住宅开放空间往往很小且管理不善,经常被低估和研究为生态便利设施。这项研究使用GIS分析和空间统计数据来探索位于美国东北部郊区县宾夕法尼亚州蒙哥马利县的1900个住宅开放空间的配置。它检查了诸如开放空间政策,细分功能和社会经济状况之类的地方特征,以识别与开放空间包裹大小和连通性相关的变量,并可以利用这些变量来培育更为有益的都市绿地配置。分析发现,开放空间有中等程度的分散,但在县内却很丰富并且聚集在一起,可以支持功能连接。直接连接还大大增加了开放空间和其他类型的受保护绿地的大小。结果表明,市政行动,例如制定开放空间标准,使用开放空间保护河岸地区以及拥有开放空间地块,都与地面开放空间的有益特征相关。
