摘要
以东北林业大学帽儿山实验林场樟子松人工林为研究对象,采用树干解析、枝解析的方法,分别于2002和2003年在老山施业区选择不同年龄、不同立地和不同密度的樟子松人工林有代表性的林分设置固定标准地15块(2002年设置7块,2003年设置8块),共获取解析样木53株,实测2298个一级枝活枝条变量因子(包括总着枝深度、方位角、着枝角度、基径、枝长、弦长、弓高)数据资料。基于理论或经验生长方程,建立樟子松人工林树冠结构静态模型及树冠动态生长模型。采用VC++6.0语言为开发平台,结合OpenGL开放式图形库,将生长模型与形态结构模型结合,建立樟子松人工林树冠动态三维图形可视化模拟系统,实现基于实测数据和生长模型的静态、动态单木和林分的可视化模拟。
This study was performed in Mongolian Scots Pine （Pinus sylvestris var. mongolica ） plantations in Maoershan experiment forest centre of northeast forestry university. Based on stem and branch analysis, data were collected from 53 sample trees in 15 plots with different ages, site conditions and densities in 2002 and 2003. The variables of 2 298 branches were measured in this paper, which included depth into crown, branch azimuth, branch angle, branch diameter, branch length, branch chord and height of branch bow. Based on theory and experience growth model, the crown static models and dynamic growth models of Mongolian Scots Pine plantations were developed in this study. The crown three-dimensional visualization dynamic graphics simulation system of Mongolian Scots Pine was established on the developing platform of VC ＋＋ 6.0 language and OpenGL through the combination of growth model and configuration structure model. The visualization simulation of static and dynamic single tree and stand based on actual measurement data and growth model was realized in this paper.
