基于百度热力图的兰州市中心城区空间结构研究

Research on Spatial Structure of Lanzhou Center City Based on Baidu Heat Map

为探索兰州市中心城区的规划空间与实际空间的耦合程度,论文以随机爬取的2018年7月21日、7月22日(休息日)及7月23日(工作日)百度热力图数据为基础,以ArcGIS 10.2为技术分析工具,分析兰州中心城区实际空间使用强度在工作日和休息日的空间变化特征,结合兰州市第四版城市空间结构规划,得出规划空间的建设与实际空间使用之间的差异,并提出相应中心城区优化建议。

For exploring Lanzhou center city planning space and real space coupling degree, this paper is based on the data of Baidu heat map on July 21,22(rest day)and 23(working day),2018,which are crawled randomly,with the ArcGIS 10.2 technical analysis tools,analyses Lanzhou center city actual space use intensity in the space variation of the working day and rest day.Combined with the fourth edition of urban spatial structure planning in Lanzhou city,it is concluded that the difference between planning space construction and use of the actual space,downtown and put forward the corresponding optimization suggestions.
