生活圈视角下郑州地区居住小区绿地空间可达性研究

Research on the Spatial Accessibility of Green Space in Residential Districts in Zhengzhou City from the Perspective of Life Circles

绿地空间可达性是评价社区生活圈绿地空间布局和服务能力的重要指标。选取郑州地区高新区某15分钟社区生活圈区域范围内的居住小区绿地空间为研究对象,运用ArcGIS10.2中的缓冲区分析、网络分析以及成本距离分析工具,综合构建绿地空间可达性量化分析模型,生成各个指标下的服务范围,并以服务范围较研究区域的面积占比等指标,尝试探索社区生活圈尺度的绿地空间可达性,为研究居住小区的绿地空间布局及服务能力提供借鉴。

The accessibility of green space is an important indicator to evaluate the spatial layout and service capacity of green space in the community living circle. The green space of residential quarters within a 15-minute community living circle area of the high-tech zone in Zhengzhou City is selected as the research object, and the buffer analysis, network analysis and cost distance analysis tools in ArcGIS 10.2 are used to comprehensively construct a quantitative analysis of green space accessibility. The model generates the service scope under each indicator, and uses the service scope to compare the area of the study area and other indicators to try to explore the accessibility of green space at the scale of the community living circle, and provide a reference for the study of the green space layout and service capabilities of residential communities.
