基于POI数据的合肥中心城区的功能区识别研究

Functional Area Identification of Hefei Downtown Based on POI Data

利用网络爬取2018年4月合肥市的POI数据,以合肥中心城区为研究对象进行功能区的识别研究,基于Arcgis软件,依据空间连接的统计结果和一定的可视化手段,得出功能区识别的结果,分析并比较不同功能区的空间分布特征,同时将功能区的识别结果与现状规划进行对比。研究结果表明,基于POI数据和相关的定量分析方法,能够比较准确快速地对城市功能区进行识别,在检验现状规划实施的同时,对未来城市功能区规划及城市的空间规划具有一定的借鉴价值。

Using the network to climb the POI data of Hefei city in April 2018,the functional area identification research is carried out in the downtown area of Hefei.Based on Arcgis software,according to the statistical results of spatial connection and certain visual means,the results of functional area identification are obtained,and the space of different functional areas is analyzed and compared.The distribution characteristics,while the recognition results of the functional area are compared with the current situation planning,the research shows that based on POI data and related quantitative analysis methods,the urban functional areas can be identified more accurately and quickly,while verifying the implementation of current status planning,it has some reference value for the functional area planning and the spatial plannin of the future urban.
