| Abstract: |
| A cellular automaton urban space(CAUP) model is proposed by introducing quantitative function value for each block of lands.This method can effectively reduce the number of unknown parameters in the CAUP model,and increase the possibility of using the model in the simulation process.By applying our model to the rebuilding process of urban space evolvement of Guilin urban area from 1973 to 1993 and then comparing this experimental result with the real satellite pictures of the city,this paper finds that the solution is right and suitable for the real application. |
