This paper presents a new model to simulate the dynamic change of multiple land uses based on praedial-block feature cellular automata.Recently,cellular automata(CA) have been increasingly used to simulate urban growth and land use dynamics.Traditional CA models simulate urban growth with regular-figure,which are invariant within a region.The regular-figure CA models have limitations in simulating dynamic urban growth in a complex region.It is considered that the development probability of cells with the irregular-figure may vary in the spatiotemporal dimensions because of the complexity of urban systems.The irregular-figure feature concept including geographical unit was attributed to the CA,and the concept model of CA was constructed based on praedial-block feature.This proposed model was used to simulate the urban growth of the Touzao Town from 2002 to 2015.The prediction of urban land use in 2015 was also carried out by using this model based on the development trajectory.The result of the simulation proved that CA based on praedial-block feature is feasible because overall accuracies was calculated by comparing the simulated patterns with the actual ones from map data.It can more truly describe geographic information,local spatial relation and evolvement rule.Therefore,it can help directly in urban planning and management.
