树皮厚度值(胸径处)是反映树种或品种形态特征的基本数据之一,也是计算某些特征值(如胸径、生长率、材积等)的媒介。为了掌握近期江苏成片林各树种组和一些主要树种的单侧树皮厚度,求得此值与带皮胸径的相关方程,减轻野外林业调查的劳动强度,对此我们进行了一些探讨。 1 资料的收集和来源 本文所涉及的原始数据主要来源于江苏 The bark thickness (DBH) is one of the basic data to reflect the morphological characteristics of species or species, and is also a medium for calculating some eigenvalues ​​(such as DBH, growth rate, volume, etc.). In order to grasp the thickness of one-sided bark of each tree species group and some major tree species in Jiangsu Province recently, we get the correlation equation between the value and the DBH and reduce the labor intensity of the field forestry survey. 1 data collection and sources The main data involved in this article mainly from Jiangsu
