摘　　要：论文充分结合帽儿山地区的实际地势环境以及现今以次生林为主的森林环境,以较完整实现帽儿山地区的三维虚拟林相为主要目的,探索实现在森林地域地形环境和相应地理信息调查清楚的情况下,根据地区实际模拟当地三维林相的可视化过程。利用Autodesk MAP软件首先对帽儿山地区已有的等高线矢量数据做进一步的处理,在图像处理软件ERDAS中生成DEM,再通过该软件提供的Virtual GIS模块,建立树木的外观模型,利用已生成的DEM以及相应林相图最终实现三维虚拟林相。To explore the terrain in the forest environment and the corresponding geographic information survey clear, this paper combines the Maoershan area and the actual terrain to secondary forest dominated forest environ- ment with a complete realization of 3 D virtual forest in Maoershan region as the main purpose according to the actual local 3 D visualization process simulation of the forest area. Firstly the contour vector data of Maoershan area for fur- ther processing by using Autodesk MAP software to generate DEM in the image processing software ERDAS, Virtual and GIS module provided by the software, establish the appearance model of trees, the use of DEM has been gener- ated and finally realize the three -dimensional virtual forest forest map.
