杉木中幼龄人工林胸径结构及预估模型

Breast high diameter structure and forecast in young and middle-aged Chinese fir plantation

分析了不同年龄杉木同龄林胸径结构变化规律,并建立了林分胸径因子与年龄因子的回归模型,联合正态分布模型可预估不同年龄的杉木同龄林胸径结构。

The variable regularities of breast high diameter structure are analyzed in even-aged Chinese fir plantation of different age. The regressive model is established between the ages and factors of breast high diameter of stands. Combined with the normal distribution model, the breast high diameter structure of even-aged Chinese fir plantation can be predicated to different ages.
