英文摘要	Based on the analysis of the general disciplinarian and the particularity for the application of Cellular Automata in geography and hydrology respectively, according to the basic principle of hydrological model and Cellular Automata, a watershed routing model based on GIS and Cellular Automata, HydroCA was created in this paper. A simulation system, Hydro_CA, by combining the HydroCA model for runoff routing with TOPMODEL model for rainfall-runoff simulation was developed and used to simulate runoff process from I April 1998 to 31 August 1998 in the study area LeAnhe Catchment in the northeast of JiangXi Province. The results of the simulation prove that the precision of TOPMODEL simulation can be improved by using HydroCA routing model from 64.7% to 71.0%. It is shown that HydroCA model is feasible to simulate the watershed runoff routing. Cellular Automata model will contribute to the distributed watershed hydrological model research and development.; Engineering, Aerospace; Remote Sensing; Imaging Science & Photographic Technology; EI; CPCI-S(ISTP); 1
