摘要
从林分结构规律出发,采用整体到个体的方法,从森林资源二类调查的林分因子的整体信息获得树木个体信息的几何特性,应用自然稀疏规律及树木竞争与生长模型来对森林空间数据进行时变性分析与仿真。其研究结果能够为树木、森林的动态过程模拟建模提供足够详细、可靠的数据源,从而实现整个虚拟森林生长的动态变化。
In view of law of stand structure, this paper adopts the whole-to-individual method to obtain individual trees geometrical characters from the whole information of stand forest management inventory, then analyzes and simulates the time-varying property of forest with the self-thinning, competition and the growth model of individual tree. Research result can provide detailed and credible data source so that it can implement the dynamic variation in the virtual forest growth.
