YIN Chang-lin1,2,ZHANG Hong-hui1,2,LIU Qin-zhi3(1.School of Info-Physics and Geomatics Engineering,Central South University,Changsha 410083;2.Changsha Planning Information Service Center,Changsha 410013;3.College of Continued Education,Guizhou University,Guiyang 550001,China)  
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.
