摘　　要：回顾了城市扩张模拟的研究进展,发现相关研究在表达城市系统的复杂性特征时存在较多问题,主要原因是未能较好地反映城市扩张与驱动因子间的相互作用与反馈机制。部分研究虽然隐含地考虑了这种"因-果"相互作用关系,但尚未形成一套成熟的框架体系,主要表现在:1)从研究深度看,反馈机制的实现尚无一套系统的方法;2)就研究广度而言,目前城市扩张模拟较少考虑多类别反馈机制的综合作用。新理论与方法(如复杂系统与网络)的引入及模型耦合等是未来基于反馈机制的城市扩张模拟研究的重要方向。This paper reviewed respectively the research progresses on urban growth modelling and feedback mechanism in their own fields,then analyzed the status and problem of the feedback mechanism in urban growth modelling.The results showed that：1）The study of urban growth modelling based on the non-spatial feedback mechanism had gotten certain achievements,been represented by the dynamic system.But it just focused the positive feedback in urban growth process.2）The CA or Multi-agent model provided a feasible but ambiguous way to present the spatial feedback mechanism in urban growth modelling.3）It was very weak in the coupling research of different feedback mechanisms.It was considered that the introduction of new theory and model coupling were effective ways to the future research of urban growth modelling based on the feedback mechanism.
