[An individual-based catchment scale forest dynamic model].
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 hm2) 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.
