兼顾周边设施的上海市游憩空间公共交通可达性研究

Study on public transport accessibility of recreation spaces in Shanghai considering surrounding facilities

  • 摘要: 以上海市为案例地,选择23个游憩空间作为分析对象,从本地居民视角切入,以公共交通为主要出行方式,兼顾周边设施,运用Python编程语言和ArcGIS软件,评价了上海市游憩空间可达性发展水平. 各个游憩空间30 min以内可达区域占比为5.79%~7.12%,240 min以内可达区域面积占比为46.37%~56.95%. 各个游憩空间可达性空间形态可以概括为圈层‒树枝状、不对称圈层‒树枝状、椭圆‒轴向和多中心圈层4种结构类型. 研究区范围内游憩者到达23个游憩空间的平均时间为127.05 min,有50%以上区域可在4 h内到达任一游憩空间. 陆家嘴周边的游憩设施步行指数最高,外围地区的游憩空间周边尚未形成集聚的游憩设施,步行指数较低. 兼顾周边设施的综合可达性差异明显,高分值游憩空间聚集于城市中心地区,低分值游憩空间分布于步行指数较低的外围地区. 兼顾周边设施的城市游憩空间公共交通可达性研究,深化了对游憩空间布局均衡性的认知.

     

    Abstract: This paper selects 23 recreational spaces in Shanghai as the analysis object. It evaluates the accessibility development level of recreational spaces in Shanghai from the perspective of local residents taking public transport as the main travel mode, taking into account the surrounding facilities, and using python programming language and ArcGIS software. The accessible area of each recreational space within 30 minutes accounts for 5.79%–7.12%, and the accessible area within 240 minutes accounts for 46.37%–56.95%. The spatial form of accessibility of each recreational space can be summarized into four structural types: circle branch, asymmetric circle branch, ellipse axis and multi center circle. The average time for recreational people to reach the 23 recreational spaces in the study area is 127.05 minutes, and from more than 50% of the area, people can reach any recreational space within 4 hours. The walking index of recreational facilities around Lujiazui is the highest; a cluster of recreational facilities has not been formed in the recreational space in the peripheral areas, and the walking index is low. Taking into account the obvious difference in the comprehensive accessibility of surrounding facilities, the high score recreational spaces are concentrated in the central area of the city, and the low score ones are distributed in the peripheral areas with low walking indexes. Discussion on public transport accessibility of urban recreation spaces involving surrounding facilities has deepened the understanding of the balanced distribution of recreation spaces.
