基于可达性分析的城市公园绿地供给研究——以广西玉林市为例

Study on Urban Park Green Space Supply Based on Accessibility Analysis: A Case Study of Yulin City, Guangxi

城市公园绿地在空间上的分布和供给水平对其服务功能的发挥有非常重要的影响。人均公园绿地面积这一数量指标忽略了可达性问题以及实际人均公园绿地水平的空间差异。另一方面,在城市绿地资源紧缺的情况下对城市公园绿地的精准化供给提出了较高要求。尝试通过基于互联网位置大数据平台的数据分析,对不同出行方式下公园绿地的可达性进行评价,并从可达性的视角提出人均有效绿地面积的概念,用以分析玉林市中心城区现状公园绿地的空间分布和供给情况,提出优化策略和方案,为城市公园绿地的布局提供新思路。

The spatial distribution and supply of urban park green space have an important impact on the play of their service functions.The quantitative index of per capita park green space area has ignored the issues of accessibility and spatial difference of actual per capita park green space level.As urban green space resources are in short supply,high requirements are raised for the accurate supply of urban park green space.With data analysis based on the Internet location big data platform,this paper has evaluated the accessibility of park green space under different travel modes,put forward the concept of effective per capita green space area from the perspective of accessibility,to analyze the spatial distribution and supply of park green space in the central urban area of Yulin city,and proposed optimization strategy and scheme based on the evaluation results,providing a new idea for the layout of urban park green space.
