居民个体活动和企业经济活动的时空关联为研究城市空间结构的形成和演化机理提供新的视角。本项目拟选择广州、北京、上海和重庆等城市为案例，以居民个体居住区位选择与日常活动、企业区位选择与日常经济活动和政府公共服务供给等活动类型为研究主体，以时空集聚、时空排斥、时空约束和时空可达等时空关联为切入点，开展多时间尺度的活动调查，并在GIS平台上，构建时空网络模型、时空集聚模型和多智能体模型，研究①个体居住选择与日常活动时空集聚与时空排斥视角下的城市社会空间结构及其时空演化机制；②典型产业企业区位选择与日常经济活动时空集聚与时空约束视角下的城市产业空间结构及其时空演化机制；③时空约束与时空可达视角下城市公共服务设施的空间配置机理；④基于时空关联的城市空间结构理论体系再思考以及⑤上述研究在城市规划领域的应用等。以期构建一套新的城市空间结构研究理论和方法体系，并推动时空间研究在城市规划中的应用。

The space-time relation of micro individual behavior and economic activities will be one of the new perspective for the study on forming and transformation of urban structure. Based on the case studies of Guangzhou, Beijing, Shanghai and Chongqing, China, taking the activities, such as people's residential location preference and daily activities, enterprises' location preference and daily activities, and the public service supplying activities as the main research items, with the perspective of space-time clustering, space-time exclusion, space-time constrain and space-time accessibility, and using the method of GIS and the space-time models such as space-time network models, space-time clustering models, and multi-agent models, this project will do some research as following: Firstly, the social structure and its spatial-temporal transformation mechanism from the perspective of space-time clustering and exclusion of individuals' activities. Secondly, the industrial structure and its spatial-temporal transformation mechanism from the perspective of space-time clustering and constrain of typical industrial enterprises' activities. Thirdly, the public services' location mechanism from the perspective of space-time constrains and accessibilities. Fourthly, the rethinking about the theory of urban structure based on the research above and finally, the application in the field of urban planning. The main aim of this project is to setting a new theory framework on the field of urban structure research, and pushing the application of space-time research in the field of urban planning.
