三维可视化技术在数字林业中的应用研究

数字林业的三维可视化是在林学和计算机图形学领域研究的一个热点,从简单的林木三维建模到辅助进行森林空间结构合理化,三维可视化技术都提供了全新的森林经营理念和生产管理方式。从树木模型、虚拟林相图、生长模型、林火模拟、病虫害监测、森林空间结构六个方面介绍了三维可视化技术在数字林业中的应用概况,并且分析了三维可视化技术对林业生产、经营、管理、决策等起到的重要作用。森林资源信息量大、涉及面广、关系复杂,因此森林资源三维可视化的研究还需要不断深入。

A Study on Application of 3D Visualization Technology in Digital Forestry

Three-dimensional（3D） visualization of Digital Forestry is a hot topic in the field of forestry and computer graphics.From simple 3D modeling of trees to aid rationalization of forest spatial structure,refreshingly different forest trade conception and production management mode are provided by 3D visualization technology.The six kinds of application situation of 3D visualization technology in the digital forestry,namely tree model,virtual forest type map,growth model,forestry fire simulation,pest and disease monitoring,forest spatial structure are summarized,and the important role of 3D visualization technology in forestry production,operation,management,decision-making and so on are analyzed in this article.There are large amount of information,wide range and complex relationship in forest resource,so furthering research on 3D visualization of forest resource are also needed.
