摘要:

绿地可达性是反映绿地合理布局、公平使用的重要指标，提高绿地可达性有助于绿地的高质量发展。基于ArcGIS网络分析法，通过可达性指数和服务强度计算，分别从空间布局和居民使用的角度对云南省普洱市城市规划区游憩绿地进行可达性分析。结果表明：游憩绿地空间布局总体合理，供给总体满足居民需求；但还存在少部分居住区可达性较差，少部分游憩绿地过渡使用的情况。根据空间布局和供给水平分析结果，从绿地空间布局和品质2个方面提出优化建议，指明今后绿地优化的重点和方向。

Abstract:

The accessibility of green space is an important index to reflect the rational layout and fair use of green space. Improving the accessibility of green space is helpful to the high quality development of green space. Based on the ArcGIS network analysis, through the calculation of accessibility index and service intensity, the accessibility of recreational green space in Pu'er city planning area of Yunnan Province is analyzed from the point of view of spatial layout and residents' use. The results show that the spatial layout of recreational green space is generally reasonable and the supply meets the needs of residents, but there are still a small number of residential areas with poor accessibility and a small number of recreational green space overusing. According to the analysis results of spatial layout and supply level, the optimization suggestions are put forward from two aspects of spatial layout and quality of green space, and the key points and directions of green space optimization in the future are pointed out.
