利用对白榆、加杨、旱柳、白腊4种纯林的“二类调查”的967个角规样点的角规控制胸径检尺的调查资料,分别对这4个树种组成的纯林的平均树高与平均胸径的关系进行了回归分析。结果表明,这4种人工林的平均树高与平均胸径之间存在着相关关系,即H=a+blnD,且相关紧密。在内蒙西部荒漠地区,用胸径估测平均树高对于人工林资源清查具有指导意义。 Based on the survey data of 967 scale points in the “second survey” of four elite stands of Ulmus pumila, poplar, willow and white wax, Regression analysis of the relationship between average tree height and average breast diameter. The results showed that there was a correlation between average tree height and average breast diameter of the four plantations, ie, H = a + blnD, and closely related. In the desert area of ​​Inner Mongolia, it is instructive to estimate the average tree height with DBH for the inventory of plantation resources.
