摘要: 从居民活动特征出发,使用手机信令数据量化测度上海郊区城镇圈空间组织特征。以工作日通勤出行、休息日非通勤出 行表征通勤、非通勤跨镇功能联系测度城镇圈空间组织。以Louvain社区发现算法测算居民跨镇活动的网络特征、使用改 进的独立指数测算城镇圈内居民活动平衡度。发现居民通勤和非通勤活动网络的组群划分结果与区级行政区划基本重 合,区级行政区划是影响城镇圈空间组织的重要因素。规划既有城镇圈内的非通勤独立指数普遍低于通勤独立指数,居 民非通勤活动显示的既有城镇圈空间组织实现程度相对较低。认为“上海2035”总体规划中的城镇圈规划实施要重视 克服区级行政区划表征的制度性因素影响,城镇圈规划实施要更加重视公共服务资源的布局和配置。利用手机信令数 据测算城镇圈空间组织的方法将有助于国土空间总体规划中城镇圈规划实施监测。

Abstract: From the perspective of resident activities, the spatial organization characteristics of Shanghai town circles are explored by using mobile phone signaling data. The commuting trips on weekdays and non-commuting trips on weekends are respectively used to represent the inter-town commuting functional linkage and inter-town non-commuting functional linkage, which are considered as the complementary dimensions for exploring spatial organization characteristics. Network patterns of intertown resident activities are explored by the Louvain algorithm, and the self-containment of town circles in terms of resident activities is measured by the modified independence index. Our results show that the sub-regions provided by the Louvain algorithm are almost consistent with the district administrative divisions, indicating that the district administrative divisions are significantly associated with the spatial organization of Shanghai suburb town circles. Besides, for most town circles, the non-commuting independence index is generally lower than the commuting independence index, indicating that the town circles are less corresponding to the spatial organization in terms of non-commuting trips. The conclusions contribute to some suggestions that the implementation of town circle planning should focus on overcoming the influence of institutional factors represented by district-level administrative divisions in Shanghai comprehensive planning, and more attention should be paid to the allocation of public service resources in the implementation of town circle planning. This paper proposes a method for measuring the spatial organization of town circles using mobile phone signaling data which will help to the implementation monitoring of town circle planning in the territorial spatial master plan.
