摘要
林木距离分布是森林结构的重要体现,林木最近距离分布的估计是应用与距离有关的单木生长模型、林分空间结构模拟与重现以及森林可视化经营的重要基础。研究提出了模拟林木最近距离分布的新途径,指出林木距离分布遵从W e ibu ll分布。结构丰富天然林的林木最近距离分布仅用2参数的W e ibu ll分布函数足以很好地表达。研究提出的描述林木最近距离分布模型是进一步用非耗时费力的因子预测距离分布的前提。
The distribution of distances is one of the characteristics of forest spatial structure and as a basis for application of individual tree growth models, for recovery of forest spatial structure and for visualization of forest stands. The study presented a new method for modelling distributions of distances to the nearest neighbours. The distribution of distances follows the Weibull distribution. The Weibull distribution function with only 2 parameters is sufficient for describing nature forest structures. The method is a precondition for further estimation for the distributions of tree-tree distances with very little effort as part of a normal forest inventory.
