摘要
基于供需均衡理念识别服务盲区并科学选取公园建设区域、明晰其建设的优先次序对优化城市公园布局具有重要的现实意义。本研究以太原市绕城高速范围内建成的公园为对象,借助高德地图路径规划的应用程序编程接口及兴趣点数据分别对公园的可达性与服务压力进行测算,以表征其供给能力与需求水平;通过叠加分析识别出太原市公园绿地服务盲区,并借助位置分配(LA)模型有针对性地增补公园绿地。结果表明:步行和骑行方式下,研究区15 min公园可达性覆盖率分别为35.6%和71.7%,公园供给能力存在不足;太原市公园绿地潜在需求大的区域主要集中在亲贤街-长风街商圈、东中环路双塔商圈,存在较明显的隐形盲区;基于LA模型提出了新增公园绿地选址建议,优化结果表明,15 min步行和骑行的可达性覆盖率分别提升至46.7%和81.0%,公园服务压力得到缓解。本研究利用网络大数据优势将居民休闲游憩需求与公园布局紧密结合起来,提升了优化选址研究的科学性和精确性,可为公园建设提供切实有效的规划方法和理论依据。
It is of great practical significance to identify service blind area,scientifically select park construction areas,and clarify the priority of parks’construction based on the co-ordination of supply-demand evaluation.With the urban parks within the Taiyuan Ring Expressway as the research subjects,we estimated the accessibility range and the service pressure of each park by using the application programming interface of Gaode map route planning and point of interest data to characterize their supply and demand levels.We identified the service blind areas of parks by overlay analysis,and used the location-allocation(LA)model to purposefully supply park green space.Results showed that the accessibility coverage rates of the parks by walking and bicycling within 15 minutes were 35.6%and 71.7%,respectively,indicating insufficient supply capacity of parks.The areas with large potential demand for park green space in Taiyuan were mainly concentrated in the business district of Qinxian-Changfeng Street and the Shuangta business district within Dongzhong ring road,which existed the obviously invisible blind areas.Finally,we proposed new park green space site selection proposal based on LA model.Optimization results indicated that the coverage rates of walking and bicycling within 15 minutes increased to 46.7%and 81.0%,respectively,and that the service pressure of parks was relieved.We combined the leisure demands of urban residents and the distribution of urban parks by utilizing network big data,which could promote the scientific nature and accuracy of the optimizing site selection and provide scientific method and theory basis for urban park construction.
