摘　　要：SketchUp软件简便易学,可迅速构建、显示、编辑三维模型,避免了其他三维设计软件的复杂性,且生成的模型简洁、精细,因此基于SketchUp软件,研究快速、高效、低成本地构建虚拟景观的方法,提出几何建模的技术方案,对几何建模和纹理映射的方法进行详尽地分析并重点介绍它们实现的方法,为减少三维模型数据量提出一些模型优化处理的相关方法,以北京建筑工程学院虚拟校园建设为实例,验证方法切实可行.SketchUp is a kind of software which is simple to learn and can establish, display, edit 3D model that is compact and refined more easily than other 3D design software. So how to reconstruct virtual landscape quickly, high efficiently and low costly based on SketchUp was considered in this paper. Technical scheme was listed here, and the implement methods of geometry modeling and texture mapping were described after detailed analyzing them. In order to reduce data size of 3d model, some model optimization methods were presented. Beijing University of Civil Engineering and Architecture is taken as an example and the good effects are acquired. Experiment results show all the relevant methods are feasible.
