| Abstract: | Cities are dynamic intricate systems, and the integrity of CA and other city models with the ability to calculate time and space have the great advantage of resolving urban land expansion problem. In this paper the concept and theory of CA and MARKOV and AHP are introduced. Through the analysis of urban land dynamic process and the attribute of other models, a compound CA model is put forward. The model that couples CA with Markov and AHP is a useful method for simulating and predicting the land use growth situation. With the help of GIS and Geodatabase, Jiangmen City is taken as an example for simulation. The result indicates that the city has a trend to expand northward and southward. The established model can be used as an virtual lab for decision support in urban planning and land policy-making. |
