The recording and simulation data of forest landscapes are massive, high-dimensional, and abstract, requiring intuitive representation. 3-D visualization is an efficient tool to comprehend possible landscape changes generated by real-world or forest landscape models. Based on current advantages of game engines (realism and convenience), we developed a platform for 3-D visualization of forest landscapes (FLV). FLV streamlines multiple software and programming languages to break barrier between geographic data and game engine and transforms outputs of forest landscape models into visualization parameters. Compared with previous 3-D visualizations, FLV has better realism, efficiency, and navigation. We used simulation data of post-volcanic eruption forest landscape recovery in Changbai Mountain as a case study and demonstrated functionalities of FLV. FLV can visualize seamlessly from individual tree to forest stand and landscape scales, and from individual year to decades and centuries temporal scales. It offers potential solutions for the digital representation of complex environmental change.

森林景观的记录和模拟数据海量、高维、抽象，需要直观的表示。3-D 可视化是理解现实世界或森林景观模型可能产生的景观变化的有效工具。基于当前游戏引擎的优势（真实性和便利性），我们开发了一个用于森林景观（FLV）3D 可视化的平台。FLV 简化了多种软件和编程语言，以打破地理数据和游戏引擎之间的障碍，并将森林景观模型的输出转换为可视化参数。与之前的 3-D 可视化相比，FLV 具有更好的真实性、效率和导航性。我们以长白山火山喷发后森林景观恢复的模拟数据为例，展示了 FLV 的功能。FLV 可以无缝地可视化从单个树木到林分和景观尺度，以及从单个年份到几十年和几个世纪的时间尺度。它为复杂环境变化的数字表示提供了潜在的解决方案。
