摘要: 基于长期跟踪复测数据,构建单木生长模型和具有时间序列的林分直径分布预测模型,并结合OnyxTREE和3Ds MAX技术,实现不同强度择伐样地不同生长时期的林分生长动态仿真。结果表明: 利用该方法进行林分生长模拟,具有更直观、更生动的效果,对森林的经营决策和林业课程的直观教学等具有重大实用价值。

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.

Key words: natural secondary forest, growth dynamics, selective cutting intensity, simulation
