摘　　要：基于CA模型,从城市规划角度,通过引入控制性详细规划层,将整个城市空间划分为不同组团片区,构建了自下而上和自上而下相结合的城市规划CA模型(UPCA),并以长沙市为例进行实证研究。结果表明:该模型简化了传统CA城市模拟模型的数据量,提高了模型的模拟精度,并增强了模型的规划决策功能,使模型具备一定的社会经济分析能力。The traditional CA model simulates the complex city system based on the from-bottom-to-top thinking, and has neglected the influence of the macroscopic decision-making to the evolution of the urban morphology. In this paper, based on traditional CA model and from the point of urban planning, the entire urban space is divided into different and organized pieces of areas by the introduction of controllability detailed planning layer. Meanwhile, the traditional CA model is improved to a combination of the from-bottom-to-top urban planning CA model and the from-top-to-bottom one, and great approved simulating results have been achieved. The results indicate that this model can simplify the data quantity of traditional CA city simulation modeling, increase the model simulation precision, and strengthen the model＇s plan decision-making function, enable the model to have the certain social economy analysis ability.
