摘要(Abstract)：

本文报道了四川的云南松树干在部三个不同部位直径 (地表直径d0 .0 0 、0 0 5m高处直径d0 .0 5、0 10m高处直径d0 .10 )与胸径 (d1.3 )的相关关系 ,利用其编制了四川云南松地径一元材积表 ,并对其在四川云南松林区进行盗伐木、滥砍乱伐木材积估计和监测森林资源消耗量等方面的应用进行了探讨。四川云南松地径与胸径最佳关系模型为二次抛物线回归方程 ,相关系数r =0 9992 17～ 0 999380 ,剩余平方和Q =179 3391～2 2 6 4 4 80 ,且d0 .10 与d1.3 相关关系最为紧密。
In this article the relationships were reported on three different parts(basal diameter,diameter of 0.05 meter high,diameter of 0.10 meter high and diameter at breast height,abbreviated as:d_~(0.00),d_(0.05),d_(0.10),d_(1.3))of Pinus yunnanensis in Sichuan and used fo work out a local volume table.Discussion was directed to uses in estimating the amount of the stolen wood and excessively cut wood and monitoring the consumption amount of Pinus yunnanensis forest,etc.The result showed the relation model between basal diameter and diameter at breast height was square regressive equation,regression coefficient(abbreviated as r):r=06999217～0.999380,residual square(abbreviated as Q):Q=179.3391～226.4480,and displayed the closest relation between d_(0.10) and d_(1.3).
