摘  要:
树木主要调查因子是指树木的直接测量因子及其派生因子。基于树木调查因子的内在联系,利用234株油松实测材料,分析了直径与树高、树干枝下高及材积的相关关系。结果表明,它们之间的相关性非常紧密,其相关指数(R)均在0 98以上。

摘  要:
The major tree measurement factors include the original measurement factors and their derived factors. Based on the internal correlations among the factors, the relationships between tree diameter and height together with that between the height from ground to the first branch and the tree volume were analyzed using the measurement data of 234 Chinese pine. The results showed that they were highly correlated with coefficients higher than 0.98.
