基于多源数据的城乡交错带空间分异及其形成机理研究：以南京市为例

城乡交错带是新型城镇化和乡村振兴战略实施的焦点区域，亟需基于多源数据深入认识其精细尺度的时空分异过程和特征，进而从从城乡相互作用视角重新认识其空间分异效应和驱动模式。本研究以南京市为例，在文献梳理的基础上，综合运用手机信令、POI、高分遥感影像等多终端大数据采集手段，结合传统的统计数据与访谈调查，基于形态和功能维度，识别城乡交错带空间分异特征与演化过程，构建城乡交错带空间分异理论分析框架，揭示不同特征类型的形成机理，评价城乡交错带内部不同功能区的效应差异及其对城乡融合的影响，提出城乡交错带不同类型区域差别化管控的政策建议。研究成果可以深化城乡交错带的理论研究，为城乡融合发展提供科学支撑。

Urban-rural fringe is a hotspot area for the implementation of new urbanization and rural revitalization. Thus, there is an urgent need to comprehensively understand the spatial-temporal differentiation process and characteristics of urban-rural fringe at the fine scale, based on multiple datasets; and to re-recognize the effect and driving mechanism of spatial differentiation of urban-rural fringe, in the perspective of urban-rural interaction. Taking Nanjing city as the case, this study will firstly identify internal differentiation of urban-rural fringe and its spatial-temporal process from both morphological and functional dimensions, based on multi-source data, such as mobile phone data, POI, high-resolution remote sensing images, survey data, questionnaires, and traditional interviews, etc. The mechanism of spatial differentiation of urban-rural fringe will then be explored under a theoretical framework. Furthermore, the social, economic and eco-environmental influences of spatial differentiation of urban-rural fringe are to be evaluated, respectively. With the above analysis, this study hopes to complement the theory on urban-rural fringe, and provide policy recommendations for urban-rural integration development.
