基于共享单车时空间活动的居住生活圈分异特征研究——以上海中心城区为例

Study on the Differentiation of Residentia lLife Circles Based on the Spatia-l Temporal Activity Characteristics of Shared Bicycles——A Case of the Central Urban Area in Shanghai

以上海中心城区为例,首先,利用共享单车大数据得出的租还时间曲线,划分不同类型的居住型虚拟租赁点。其次,详细刻画这些租赁点与周边租赁点的OD簇联系特征。再次根据其骑行特征差异对居住生活圈进行模式识别。最后,选取若干典型模式的骑行生活圈对其空间布局结构加以解析,并针对骑行生活圈构建中的主要问题提出改善建议。

Taking the central urban area in Shanghai as an example,the types of residential virtual rental stations are divided according to the rental and return volume profiles obtained from the bicycle-sharing big data firstly.Then,the temporal-spatial characteristics of the OD clusters between these points and the surrounding ones are analyzed in detail,and the pattern recognition of various life circles based on the cycling characteristics differentiation are carried out.Finally,several life circles with typical cycling link patterns are selected to compare their different spatial layout structures,and the suggestions on the construction and improvement of cycling life circles are put forward.
