摘　　要：以小陇山林区日本落叶松人工林156块样地调查数据,应用理查德曲线进行林分平均树高和胸径生长模型的拟和,通过回归假设F检验,拟和的生长模型,在F0.05水平与实际值差异不显著;利用拟和的导向曲线方程,以树高为基础,将小陇山林区日本落叶松林分立地划分为5个地位级。同时以小陇山沙坝实验基地引种试验林为例,分析了林分生长、单木生长过程和趋势。Based on the research data of 156 of Larix leptolpis in Xiaolongshan forest area applying Richard＇s e-quation curve to make study on the fitted value of mean tree height of stand and diameter of breast height of the growth model.Through regression hypothesis F testing,the difference between fitted growth model and actual value under F 0.05 level is not significant.Using the curve equations and based on the height,Larix leptolpis site in Xiaolongshan forest area was divided into five site class.Take the introduction and cultivating stand from Shaba experimental bases in Xiaolongshan for an example,the stand growth,the tendency or process of single-tree growing were analyzed in this paper.
