摘要
本研究以天水市中心城区公园绿地作为研究对象,结合天水市遥感影像图、道路网交通图、人口数量分布图、主要公园绿地分布图等,利用ArcGIS网络分析功能,对步行、骑行、机动车三种出行方式下,公园绿地的服务面积及服务人口以及不同城区公园可达性进行对比分析.其步行方式下 5 min内的公园绿地服务面积比平均为 4.16%,15 min内的服务人口比为平均为 39%;在骑行方式下 10 min内仍然有 15%居民无法到达公园及机动车方式下 5 min内依然有 40%公园绿地无法到达.
Abstract
This study focuses on the park green spaces in the central urban area of Tianshui City.By utilizing remote sensing imagery,road network maps,population distribution maps,and major park green space distribution maps,along with the application of ArcGIS network analysis,a comparative analysis is conducted on the service area,population served,and accessibility of park green spaces for pedestrians,cyclists,and motorized vehicles.The average area ratio of park green space within 5min is 4.16%,and the average popu-lation ratio within 15min is 39%;15%of residents cannot reach the park within 10min and 40%of the park green space cannot be reached within 5min of motor vehicle mode.
