摘要
城市功能分区结构研究可以检验城市用地功能是否合理并辅助优化城市空间结构。文章以济南市城区功能用地为例,基于地理信息系统(GIS)核密度分析方法,利用网络爬取的高德地图兴趣点(POI)数据研究了城市功能分区结构,并利用百度热力图验证各功能用地类型与人口流量空间分布的一致性。结果表明:居住用地、物流仓储用地、交通附属设施用地及绿地与广场用地分布合理;工业用地在西部和东部地区人流集聚程度较低;公管用地和公共设施用地在南部地区的人口发展潜力较大;商业用地聚集人流作用明显;各功能用地处于发展阶段,整体呈现中心集聚分布广、两翼离散少覆盖的模式,但总体趋向多核心、少聚集、覆盖广的方向发展。
The study of urban functional zoning can test the rationality of urban land use function and assist in optimizing urban spatial structure.Taking the functional land use of Jinan as an example,based on the method of GIS core density analysis,this paper studies the structure of urban functional zoning by using POI data of Gaode Map crawled by the network,and uses Baidu thermal power to verify the consistency between the types of functional land and the spatial distribution of population flow.The results show that the distribution of residential land,logistics and warehousing land,traffic ancillary facilities land,green space and square land are reasonable.The people agglomeration of industrial land in western and eastern areas is low.The population development potential of public management and public facilities land in the south is great.The effect of commercial land on aggregating human flows is obvious.The functional land is at the stage of development,showing a pattern of wide centralized distribution,scattered wings and less coverage,but the overall trend of multi-core,less aggregation and wide coverage.
