摘要
树木的叶形可以看作一个平面几何图形。这种几何图形可用解析方程给予表达,我们把这种解析方程称为叶形曲线方程。由于叶形是一个左右对称,而上下不对称的图形,也就是说叶的最宽处绝大多数不在叶的中部。
Based on observation and study, 3 curve equations for various leaf shapes,ellipse, oval and spindl, are advanced. These models provides scientific basis and available methods for calculating leaf areas of broadleaved trees.
