摘　　要：城市公园绿地作为户外体力活动的首选场所,可有效降低慢性疾病发病率,实现"未病先治"的健康理念。研究从体力活动服务供需平衡的视角,以多源数据空间可视化方法,对深圳市三区的综合公园和社区公园布局的评估和优化。首先,基于自主研发的移动端公众参与地理信息系统(PPGIS)获取体力活动VGI数据,并将其空间可视化形成为服务供给压力分级图。其次,基于高德地图开放平台获取POI数据,并将其空间可视化形成为服务需求压力分级图。最后,将服务供给压力分级图和服务需求压力分级图进行叠图可视化分析,获得服务盲区,依此对城市公园空间布局进行优化调整。本研究旨在促进"绿体结合",满足人们日益增长的休闲体力活动需求。As the first choice for outdoor physical activity of urban residents,the green space in urban parks can effectively reduce the incidence of chronic diseases in humans,and thus realizing the health concept of“treatment before disease”.From the perspective of the balance between the supply and demand of leisure physical activity,the study evaluated and optimized the layout of comprehensive parks and community parks in the three districts of Shenzhen City by visualizing spatial multi-source data,such as VGI data,POI data,and open street map(OSM)data.First of all,the geographic coordinate information of the existing urban parks is transformed into information points on the ArcGIS platform.Then,the information points of the urban parks are made into discrete points to generate the Tyson polygon,which is the service range of the leisure physical activity of each urban park.Secondly,the front end of the Public Participation Geographic Information System(PPGIS)is equipped with a program on the WeChat platform.Based on the PPGIS mobile terminal,VGI(Volunteer geographic information)data such as coordinate information,personal attributes(such as gender,age,health status,education,etc.)and physical activity attribute information(activity category,intensity,activity period,activity frequency,etc.)are obtained.The study has obtained 68,703 pieces of VGI data for six consecutive months(from March to August 2019).The ratio of the number of VGI points within the service area to the urban parks’area is calculated,which is the service pressure of leisure physical activity in the green space of each urban park,and is presented in a numerical terms.Subsequently,the existing physical activity service supply level and service scope of urban parks are connected,and the data will be visualized as a service supply pressure classification map on the ArcGIS platform.The natural break point classification method is used to classify the results,and the higher the level is,the greater the service pressure is.Thirdly,based on the API port
