摘要: 以甘肃小陇山白皮松(Pinus bungeana Zucc.)天然次生林为研究对象,通过树干解析分析其生长指标的生长过程。结果表明:胸径、树高、去皮材积的总生长量的变化均呈现递增趋势。胸径和树高在幼年时期生长较慢,随年龄的增长生长速度先增加后减缓,呈现“慢—快—慢”增长趋势。材积总生长量在0~15 a增长缓慢,15 a后开始增长迅速,到63 a仍保持增长趋势,未结束生长期。白皮松胸径、树高、去皮材积与胸径生长模型均以三次曲线函数为最佳,而“胸径-树高”模型则以幂函数方程拟合为最佳。

Abstract: The growth regularity of Pinus bungeana was investigated in a natural secondary forest in Xiaolongshan,Gansu Province,China.The growth processes of Pinus bungeana growing indexes were analyzed based on the analysis of tree trunks.The results showed that the total growth increment of diameter at breast height(DBH),tree height(H),and volume of wood(V) all showed increasing trends during the whole growth periods.The growth of DBH and H showed a slow increase during 0~15 a,and then increased rapidly as tree-age increased to 15~40 a,but a relative slow increase during 40~63 a.The total V of P.bungeana increased slowly during 0~15 a,and then it increased rapidly and remained a rapid increase till the end of this survey.DBH,H and V of P.bungeana were fitted better with cubic curve.The “DBH-height curve” were fitted better with power curve equation.

Key words: Pinus bungeana, stem analysis, Xiaolongshan, increment, growth rate
