摘要
本文在观察和测算的基础上,提出了一类阔叶树的叶形方程,并对方程进行积分,求出了计算这类阔叶树叶面积的通用公式。从1980年应用至今证明,用这个通用公式计算这类阔叶树的面积,方便、简捷、精度高,现介绍如下。
Based on observations and measurements,a leaf morphological equation of a kind of broad-leaved trees is proposed,by integration of which,a general formula is obtained for calcu-lating the loaf area of this kind of broad leaved trees.The formula is simple,convenientand highly accurate.
