Abstract: Duc to the changing of the requirement and the application aim of the forest simulation systems, this paper presentd a process-driven method of component assembly for forest simulation system This method designs and imple- menu the component models and the interfaces of forest simulation components,and reuses the business processes and computation algorithms by assembling software components. It can solve the existing problem that the forest simulation system is difficult to quickly build or reconstruct. In addition, this method is successfully applied to develop the forest simulation systems,and it can achieve rapid construction and reconfiguration of forest simulation systems. The applica- dons show that the process driven method of component assembly for forest simulation system proposed in this paper can significantly reduce development cycle and development difficulty compared with other methods, such as code-level reusing, redevelopment.
