摘　　要：通过外业测量获得数据并用AutoCAD绘制校园地形图及树木点图,对校园所有树木进行拍照和属性调查,利用SketchUp软件的建模技术,以DEM数据可视化时得到的三维地形模型为基础,对北京林业大学校园树木进行了三维建模仿真,实现树木三维可视化,并结合地理信息系统管理平台同步树木属性信息查询,实现了树木高效真实的可视化效果.By using data obtained from outside measuring and AutoCAD technology, campus trees and its property have been photographed and surveyed. Based on three-dimensional terrain mode which obtained by SketchUp modeling software and DEM data visualization, the campus trees of Beijing Forestry University have been operated in three-dimensional modeling and simulation, and achieved three-dimensional visualization. Combined with geographic information systems management platform and synchronization trees property information, we achieved a real and efficient visualization of trees effect.
