摘　　要：研制了基于个体的在景观尺度上运行的森林动态模型CFDM(individual-based catchmentscale forest dynamic model),介绍了CFDM模型的研制和检验过程,以及GIS技术的应用、气候和生理因子的参数化.对卧龙保护区一个139hm2小集水区进行了400年的模拟(包括地形数据的预处理、改进的山地小气候模型的运算和森林动态模拟).结果表明:CFDM模型能够描述林木个体的生理过程与空间分布,进而实现对整个集水区范围内森林的空间格局及其动态的模拟.In this paper, an individual-based catchment scale forest dynamic model was developed, and applied to a 400 years simulation of a real catchment. The simulation included pretreatment of topographic data, running of modified MTCLIM, and simulation of forest dynamics. The development and validation processes of this model were described, and the details of the model, including the application of GIS and the parameterization of climate and physiological factors, were presented. The simulation results of a real catchment （ 139 hm^2 ） in Wolong Reserve showed that this model could describe the physiological processes and spatial distribution of tree individuals, and realize the simulation of the spatial pattern and dynamics of forest in whole catchment.
