摘　　要：树木三维建模是构建虚拟森林景观的主要环节,也是三维林业地理信息系统的基础。目前,面向GIS的树木建模主要采用贴图法等静态的建模方法,无法表现树木的动态特性。为了形象表达三维场景树木变化的动态,运用3ds max软件,结合ArcGIS的二次开发功能建立了不同状态的树木模型,并在此基础上动态改变不同的树木模型的大小,以达到树木动态生长的形象变化。本系统运行顺畅,动态变化形象,且可以满足不同用户的需求。Tree＇s 3D modeling is the main links of constructing virtual forest landscape,and is also the foundation of 3D forestry Geographic Information System（GIS）.The current tree-modeling used in GIS are mostly based on pasting and other static methods,which are not able to present dynamic characteristics.In order to show the dynamic changes of trees in 3D scene vividly,the 3ds max software was used,combining with ArcGIS as the secondary development to establish various tree-models.Furthermore,to present the dynamic changes in the growth of the trees,the dimensions of various models were presented to exspress dynamic changes of tree growth.The system operates smoothly with a vivid dynamic changing image,and can meets various customers＇ need.
