摘要
油松在陕西华山分布很广,为估算古树年龄,采集了不同海拔油松胸高处、西南向的枝条,运用WindendroTM 2005a年轮分析仪测定了油松枝条圆盘的年轮数。结果表明:枝条的直径与年龄间存在较好的相关关系,建立的枝条直径与年龄的回归模型可用于古树年龄的估算。
Pinus tabulaeformis is extensively distributed in Huashan mountains of Shaanxi. Branches of the tree species were sampled from different elevations to estimate their ages. The instrument an- nual growth ring analyzer （WindendroTM 2005a） was used for detecting each age of sample discs. The results indicated that diameters of branch closely related to their ages and the regression model could better predict ages of ancient trees.
