According to the principle of the Chinese Soil Taxonomy and based on the characteristic soil horizons identified, the soils were classified into sixteen soil series, of which basic properties and distribution were determined preliminarily.

But the present GIS cannot completely express the temporal information and spatial-temporal relationship of geographical entities, lacking the capability of spatial- temporal analysis and dynamical modeling. Cellular Automata (CA) are a kind of dynamically modeling framework from bottom to top and possess the capability of modeling spatial-temporal evolvement process of a complicated geographical system. To proceed with the principle and features of CA, the paper introduces the method for structuring the model and explore feasibility and operability of the CA model in modeling and forecasting spatial-temporal process of Land Use/Cover Change (LUCC). In the end, status, existing problems and prospects of its application are analyzed. Key words Cellular Automata (CA)ModelLand Use/Cover Change (LUCC)Spatio-temporal simulation
