Abstract:Based on the long-term tracking retest data to construct the individual tree growth model and time series predicting diameter distribution model.Then use OnyxTREE and 3Ds MAX to achieve the stand growth dynamics simulation of different growth stages in different selective cutting intensity samples.The results show that using this method to realization of stand growth simulation have more intuitive and vivid effect,and have great practical value on the forest management and intuitional instruction of forest course.
