Abstract: UrbanSim was used to explore the spatial interaction of urban residence and workplace in Yichang City of Hubei Province. The simulation of urban spatial dynamics from 2010 to 2015 highlighted that the population and employment in Yichang would agglomerate towards the urbanized areas along the Yangtze River. The authors built a coupling mechanism between the residential and employment location choices in the models by sharing several independent variables so as to reveal the interaction between households and jobs at micro-level, which was previously absent in the operational model of UrbanSim.

Key words: residence, workplace, interaction, UrbanSim, Yichang

摘要： 以宜昌市为例, 从居住空间和就业空间的互动关系入手, 采用基于微观模拟的大尺度城市模型UrbanSim, 模拟城市未来的空间动态。结果表明, 2010?2015年, 宜昌市的人口和就业共同向沿江重点城镇化区域集聚。通过家庭区位选择模型和就业区位选择模型的标定, 以共享影响因素的形式, 突破了UrbanSim在家庭区位选择模型和就业区位选择模型上分离执行的局限, 从微观个体层面实现了居住空间与就业空间的互动机制。
