摘　　要：探究城市公园绿地的可达性与人口健康水平的相关性,可以为公园绿地的规划建设提供科学依据。本文以惠州市中心城区为研究对象,通过网络爬取、人口普查数据以及高德地图步行路径规划等多源数据,依据各公园绿地的规模,设置不同的服务半径,提出一种基于改进多服务阈值的两步移动搜索法,计算惠州市中心城区步行交通模式下公园绿地的可达性。利用双变量局部空间自相关方法,分析城市公园绿地可达性的空间分布差异与人口健康水平的相关性。结果显示:惠州市中心城区公园绿地的可达性空间分布差异显著,可达性较高区域分布在中心区域以及西部区域,以及公园周边地区,集中在龙丰街道、江南街道、桥西街道和桥东街道;惠州市中心城区的公园绿地的布局与人口健康水平存在空间相关性,其中江南街道公园绿地供给充足且人口健康水平较高。研究结果表明,公园绿地的可达性在一定程度上影响人口健康水平,未来在健康城市的建设中可适当增加公园绿地面积或数量。To explore the correlation of urban park green space accessibility and population health,can provide a scientific basis to the planning and construction of park green space.In this study,the central city of Huizhou was selected as the research object.Based on the data of Web crawler,population census and map walking path planning in Josiah Goddard,different service radius was set according to the scale of green space in each park,a improved multi-service threshold two-step floating catchment area method was proposed to calculate the accessibility of park green space in central Huizhou city under pedestrian traffic mode.By using Bivariate Local Spatial Autocorrelation Method,analyze the correlation of spatial distribution differences of accessibility to urban parks green spaces and population health levels.The results showed that there was a significant spatial difference in the spatial distribution of accessibility of parks and green spaces in the central urban area of Huizhou.The high accessibility areas were located in the central and western areas,as well as the surrounding areas of the park,concentrated in Longfeng Street,Jiangnan Street,Qiaoxi Street,and Qiaodong Street;There is a spatial correlation between the layout of green space and the health of the population in the urban area of Huizhou,Among them,Jiangnan Street has sufficient supply of parks and green spaces and a high level of population health.The results show that the accessibility of park green space affects the health level of the population to a certain extent,and the area or quantity of park green space should be increased in the construction of healthy cities in the future.
