村镇聚落网络联系的手机信令探索——以中山三乡镇为例

Exploring the Spatial Network of Rural and Urban Settlements through the Lens of Mobile Phone Signaling Data:A Case Study of Sanxiang Town in Zhongshan

村镇联系的结构形态是城乡经济社会复杂关系的综合反映,如何测算村镇聚落联系、构建村镇聚落发展模式是研究村镇聚落体系规划布局的重要议题。以中山三乡镇为例,利用手机信令数据测算村镇聚落的多层级网络联系,并结合自容性、群集性、网络效率等指标分析村镇聚落的网络结构特征。结果表明,三乡镇呈现簇群式的空间联系结构,具有自上而下的垂直联系和多层级相互交织的复杂网络特征;行政边界对村镇聚落联系的约束作用较小,而自然地理环境、道路交通条件、土地混合程度等对聚落联系的影响更大;作为沿海发达的半城镇化地区,工作日聚落联系的群集性较高,反映案例村镇联系不再是向心式的单一指向而呈现出网络化的水平多向联系;节假日村镇联系降低,整体网络效率、群集性也更低,但与中心城、外镇的联系比例增加,村民休闲消费的空间跃迁现象明显。

The structural form of connection between villages and towns is a comprehensive reflection of the complex connection between urban and rural society and economy.It is also an important topic to measure the connection between villages and towns,and construct the development model of them in the study of the planning and layout of rural and urban settlement system.Taking the Sanxiang town in Zhongshan city as an example,this paper attempts to use mobile signaling data to measure the spatial connection between the rural and urban settlements,the settlements and the city center or other towns.That is,to reflect the interaction process by the spatial linkages of human mobility,and to analyze the network structure of rural and urban settlements with the self-compatibility,clustering and network efficiency.The result shows that the Sanxiang town has cluster-form spatial connection structure,and has the complex network characteristics of vertical connection from top to bottom and multi-level mutual feedback.Meanwhile,we also find that administrative boundaries have less restrictive effect on the connection between rural and urban settlements,while geographical environment,road traffic conditions,land use mixing degree and other factors have more prominent influence on the interaction of them.As a coastal developed semi-urbanized area,the clustering of workingday settlement network is relatively higher,reflecting that the case of rural and urban settlements linkage is no longer a centripetal single direction,but a network of horizontal multi-direction.On national days,the links between rural and urban settlements decrease,and the whole network efficiency is comparatively lower.However,the proportions of the links between rural settlements and city center or other towns have increased,illustrating that spatial transition of villagers'leisure consumption behaviors is more universal on the holiday.
