摘  要：
为进一步构建动态3D树冠生长模型和数据分析应用,以1株亚美马褂木孤立木数码照片为材料,基于SketchUp软件模拟该单株树冠和不同分段树冠曲线旋转体3D树冠建模以及相关参数分析,结果表明:建立了不同树冠曲线旋转体树冠模型,比较各模型参数,结果表明:9点分4段树冠曲线模型体积等适用性较好。该模型为树冠三维建模及参数应用初探,可作为构建整个树冠生长基础构建。

摘  要：
In order to further construct tree growth model by dynamic 3Dand data analysis application,taking digital photo of individual tree of Liriodendron sino-americanum as material,the tree crown from individual tree of Liriodendron sino-americanum was simulated and estimated by the digital photo based on SketchUp.The results showed that tree crown was divided by 9points and crown shape was made up of 4curves to some length extent.The model of tree crown was simulated and parameter was estimated based on SketchUp.According to different crown curves,the 3Dmodel was available to comparation to formula method,while model of4 curves dependent on 9point was better in 6 models on index of crown volume.The original 3D model was processed by a series of tools in combination to physical data.It would further develop configuration for 3Ddynamic crown growth,for the future related application by SketchUp.
