【摘要】 本文介绍了一种利用函数插值和数值积分计算阔叶树叶面积的新方法。对常见阔叶树种的计算结果表明,此法简便易行,且计算精度高,具有一定的推广价值。 计算指出,阔叶树叶面积与叶片的各种特征参数之间均有一定的相关性,但与叶长和叶宽的乘积相关性最好。 文内给出了我国南方几种常见阔叶树叶面积计算的回归关系式。更多还原

【Abstract】 In this paper, a new method for measuring and computing the leaf area of leaf trees by means of function interpolation and numerical integration is presented. The counted results bear out that this method is easy to apply and has higher accuracy. Computations show that each parameter of the leafblade is somewhat related to the leaf area but the most important one is the product of the leaf-width and leaf-longth. Some regression equations for counting the leaf area of common leaf trees in South China are also incorporated.更多还原
