The cellular automata method is a useful tool for analyzing discrete spatio-temporal dynamics. However, the method holds a disadvantage due to the difficulty of representing variation of density and mix of the land uses. To overcome this obstacle, I have proposed an approach based on a 3-D spatial pattern. This rule of dynamics is similar to that utilized by White, Engelen e Uljee (1997). In order to demonstrate the results related to the use of a 2- and 3-D pattern, the paper sets out the proposed model and the experiments which were carried out within specific theoretical contexts. Conclusions are drawn on the utility of the present approach.
