Research on the Simulation of Urban Land Use Change Based on GIS and CA Models - A Case Study of Longgang District, Shenzhen City

In this paper we emphasize on the technology research depending on the CA model which have powerful computation function and spatial analysis ability of GIS to simulate and forecast urban land use change in Shenzhen city. We reconstructed and extended conventional CA model from three aspects including model run-time, influencing factors, transforming rules and finally integrate GIS into CA model by AML language. The experimental result shows that the experimental model can better simulate and predict urban land change and the result reached the expectant aim, it can offer service for the administration to institute reasonable urban developmental programming, while it also has directive signification for realizing urban continuable development.
