基于小区位置信息的GIS公园可达性分析——以上海市虹口区为例

Park Accessibility Analysis Based on Location Information and GIS--Taking Shanghai’s Hongkou District as an Example

城市公园绿地是城市中重要的休憩场所,具有重要的社会和生态效益,是城市建设用地、绿地系统和市政公用设施的重要组成部分,也是衡量城市居民生活质量的一项重要指标。其空间可达性是研究公园设计合理性的方法之一。本文以上海市虹口区的公园为例,结合实地调研中获取的公园入口位置数据以及从网络中抓取的小区位置数据,应用GIS的可达性分析工具,分析公园入口位置与小区位置情况之间相关的关系,并计算人们在步行和骑行的交通模式下所用的不同时间成本,提出基于骑、步行可达性的公园入口位置的分布布局建议。

Urban park greenbelt is an important rest place and natural landscape in the city,with important social and ecological benefits.It is an important part of urban construction land,urban greenbelt system and urban municipal public facilities,and an important index to measure the quality of life of urban residents.Its spatial accessibility is one of the methods to study the rationality of park design.This paper,taking the park in Shanghai Hongkou district as an example,combining location data of park entrance through field research and village location data captured from the network,analyzes the relationship between the entrance position of the park and the location of the housing estate,calculates the different time costs of people in the traffic mode of walking and cycling,and proposes the overall arrangement of the entrance position of the park based on the accessibility of riding and walking with GIS Accessibility analysis tool.
