Abstract: Forest composition,structure and dynamic changes in the ecology of forests have been a hot issue.Because of the complexity of forest structure,how to use a simple model to simulate forest structure is a difficult problem.This paper mainly introduces the principles of L-system,and L-system generates a single conifer tree and broadleaf tree,which combines ZELIG model to generate complex conifer forest scenes.The study shows that this method can easily generate more complex forest scenes.

Key words: L-systems, ZELIG model, forest scene simulation

摘要: 森林的组成、结构及其动态变化一直是森林生态学研究的一个热点。由于森林结构复杂,如何用简单的模型模拟森林结构是一个难点问题。主要介绍了L-系统的原理,并用L-系统生成了单棵针叶树和阔叶树,进而结合森林生长模型ZELIG生成了复杂的针阔混交林场景。研究表明采用该方法很容易生成比较复杂的森林场景。
