摘要
在回顾城市空间演化研究发展轨迹的基础上,提出复杂适应性系统理论适合于研究城市化进程中出现的各类复杂问题,对比了复杂性研究方法中的元胞自动机、分形以及多主体方法在城市土地利用空间演化中的应用,得出多主体建模的方法更适宜研究具有高度复杂性的城市空间演化问题的结论。在此基础上,采用自下而上的仿真思路,着重从建模思路、主体行为描述和通信模型三方面阐述和分析了构建城市空间演化仿真模型的多主体方法,而从发现并分析城市中家庭、政府、企业、开发商等微观主体的交互行为以及这些行为是如何导致城市土地利用空间上的宏观演化。
Based on the review of urban spatial evolution research, this paper proposes that Complex Adaptive System（CAS） theory is fit for research of urban problems. Through comparing Cellular Automata and fractal method with Multi - agent method applied to urban spatial evolution research, a result that Multi - agent is the most feasible and effective method in the research on completely complicated urban spatial evolution is concluded in this paper. Based on this ,a research framework from bottom to top is introduced, a multi - agent - based urban modelling method is then proposed and analysed to further understand urban spatial evolution from three aspects the thought of modelling, description of agents acts and correspond model, in which the viewpoint that the general behaviour of urban spatial evolution is produced by the combination of actions of the various agents in the urban, such as households, governments, enterprises and land agent, is argued.
