基于手机健身数据的城市街道健康服务功能研究

城市街道是城市空间的基本单元,承载着多元的城市生活。本研究基于手机APP共享的健身数据,以街道线性体育活动为研究对象,从健康视角认知街道空间属性和特征。运用VGI-GIS的方法,在信息矢量化和可视化的基础上,从时间和空间2个维度,对城市街道的健康服务功能进行描述。基于运动热点空间的分布格局,研究在空间集聚、建成环境和人群收入3个层面上进行分析。结果表明,街道的空间连续性对健身活动有促进作用,大型公园和高校对健身活动有巨大的吸引力,公交站点对健身活动有多方面的影响,不同收入阶层健身活动差异明显。多元化的热点空间模式为提升街道的健康性提供了因地制宜的可能性。以健康为导向的城市设计探索采用临时封闭街道,在商业和办公区域周边增设户外体育设施等措施,提升街道的健康服务功能。

Urban Street Health Service Function Based on Mobile Fitness Data

Urban streets are the basic units of urban space, which carry a diversity of city life. The study is based on fitness data shared by mobile phone applications, taking street linear sports activities as the research object, as well as recognizing street space attributes and features from the perspective of health. Under the VGI-GIS method and on the basis of information vectorization and visualization, the health service functions of urban streets are described in two dimensions: time and space. Based on the distribution pattern of popular sports space, the research is conducted on the three levels of spatial, which include agglomeration, built environment and crowd income. The results show that the spatial continuity of the street has a positive effect on fitness activities. Large parks and universities have great attraction for fitness activities. Bus stops have many influences on fitness activities. The diversified popular space models provide the possibility of improving the health of the street in accordance with local conditions. In health-oriented urban design, measures should be taken to temporarily block streets, adding outdoor sports facilities around commercial and office areas to enhance health services of the streets.
