摘要
大数据在城乡规划领域的应用越来越广泛,本文利用网络电子地图爬取到2020年5月南宁市的各类POI数据,依据POI数据所具备的空间属性信息,借助ARCGIS软件进行整理划分,通过空间连接获得统计结果再进行一定的可视化,识别到南宁市主城区的单一用地功能区和混合用地功能区,分析并比较不同功能区的空间分布特征,同时针对城市功能区识别的结果,多角度、多方式验证了识别的精度,精确高效地梳理了南宁主城区城市功能空间结构。
Big data is more and more widely applied in the field of urban and rural planning. This paper uses the network electronic map to climb all kinds of POI data of Nanning in May 2020. ArcGIS software is used to sort out and divide the spatial attribute information of POI data. The statistical results were obtained through spatial connection and then some visualization was carried out to identify the single and mixed land use functional areas in the main urban area of Nanning city. Aiming at the result of urban functional area identification, the accuracy of identification is verified from multiple angles and ways. The spatial structure of urban function of Nanning main urban area is sorted out accurately and efficiently.
