Virtual landscape is one of the important part of virtual reality technique in recent years.Virtual flower as an important research object of virtual landscape,it’s structure is complex and diverse, consequently,it’s so difficult to simulate.This article according to the method of visual modeling, puting forward a kind of method,which special y used in virtual flower modeling. And with this method we get a high efficienc in modeling flower and vivid flower model.In addition,this article introduce a method about how to develop a systerm about roaming systerm of flower landscape.So,this paper has some help and value to vitual flowers landscape modeling and roaming syserm development.% 虚拟景观是虚拟现实近年来的研究热点之一，虚拟花卉作为虚拟景观中重要的研究对象，由于其形态结构复杂、变化多样，因此虚拟仿真难度较高。本文根据可视化建模的相关方法，提出一套系统的、专门用于虚拟花卉景观的可视化建模方法，并通过实验证明了该方法具有建模效率高、模型逼真自然的特点。此外，本文还介绍了如何基于VRPlatform平台，快速实现花卉景观交互式漫游系统开发的方法。本文对虚拟花卉景观建模和漫游系统开发有一定指导作用和价值。
