摘要
借助新浪微博开放平台提供的基于位置服务,获取微博签到大数据,通过地理信息系统技术将郑州市区活动空间可视化,分析郑州市群体活动空间的总体特征,比较基于活动频次与基于人口规模空间的等级体系,讨论郑州市城市活动空间的极化原因,发现城市活动空间依然对人口等级存在依赖性,地理距离的作用仍然是导致空间极化的最主要原因.
Abstract
By using location-based service (LBS) provided by Sina micro-blog open platform,check-in mass data was obtained.Based on GIS technology,visualization of the activity space of Zhengzhou was realized,general characteristics were analyzed.The hierarchy system on the basis of activity frequency and population scale space was compared.It was found that the urban activity space is still dependent on the population level,and the role of geographical distance is still the main reason for the spatial polarization.
