摘要
林木的形态结构受到树种或林木个体的遗传因素(激素信号、养分竞争等)和立地条件、经营措施以及林木的竞争状态(光照分布、温湿度、农艺措施等)的影响,因此,掌握各种因子影响林木生长过程的机制对于林业生产和精准林业研究与实践非常重要,但如果实时地对实际林木进行生长过程影响因子研究,则存在很大的时空局限性和很高的测试成本,因而采用虚拟技术开展林木生长过程研究引起国内外的高度关注。系统地综述了国内外开展林木虚拟生长研究的7种建模方法和10种建模工具,然后提出基于林木虚拟动态生长模拟的"林木云"研究展望和基于计算机视觉系统的林木三维建模方法及相关建模工具的研究建议,并分析了林木4D虚拟动态生长模型等,从而促进林木虚拟动态生长技术研究。
The morphological structure of forest trees are affected by tree species or individual tree genetic factors（hormone signal and nutrient competition）, site conditions, management measures and competition status of forest（light distribution, temperature, humidity, and agronomic measures）. Mastering the mechanism study on the determinants of the forest trees growth process is very important for the forestry production and precision forestry research and practices. The real-time field survey of the determinants of the forest trees growth process is constrained greatly by time and space, and requires high test cost. Therefore, applying virtual technology to conducting the research on the forest trees growth has drawn great attention at home and abroad. This paper systematically reviewed 7 modeling methods and 10 modeling tools for studying the virtual forest tree growth,proposed the research prospect of forest tree cloud based on the simulation of dynamic growth of virtual forest trees, suggested on computer vision system based 3D forest trees modeling and the modeling tools, analyzed the models of forest trees growth in 4D to promote the research on the technology of the virtual dynamic growth of forest trees.
