【摘要】 树木的生长不仅受到自身遗传因素的影响而且还受外界环境条件的影响。以杉木为例,基于实测数据建立的蓄积量随林龄增长的生长模型以及影响林木生长的立地因子,以实现林分中的杉木林蓄积量可视化表达。在3D Max中构建了杉木三维形态几何模型,结合杉木生长模型与形态模型,采用AE+VB.NET编程,实现了基于ArcScene的杉木林蓄积量动态可视化,能直观地反映杉木林蓄积量随立地条件和生长模型的生长状况,对于林业生产信息化和林场的管理、经营和决策具有很大的实用价值。更多还原

【Abstract】 The growth of the trees is influenced not only by genetic factors and also by external environmental conditions.Taking Chinese firs for example,this paper,based on measured data,established the growth model of volume correlated to the stand age and site factors that influence the growth of trees.The research is helpful to realize the visualization of Chinese fir stand volume.Three-dimensional geometric model of Chinese fir is constructed through 3D Max.On the basis of the growth model and the configuration model of Chinese fir,the dynamic visualization of Chinese fir volume was realized based on ArcScene by adopting AE+VB.NET programming.It is possible to directly manifest the growth conditions of Chinese fir volume according to the site conditions and growth model and is of high practical value to forestry production information,the management,operation and strategy of the forest farm.更多还原
