Ⅰ引言迄今为止,对于作为林业经营和调查工具的干形方程,已有很深的研究,但这些研究在理论上几乎与生物学生长过程毫无联系。目前,干形研究的目的在于掌握树干材积、估计林分的生长和表示树干削度。为更好地解决这类问题,我们借助子生长和动态理论修改了以前的实验或经验干形方程。 I. INTRODUCTION So far, there has been a great deal of research on the dry-form equations as a tool for forestry management and investigation, but these studies are virtually unrelated to the biological growth process in theory. At present, the purpose of dry studies is to grasp the volume of the trunk, estimate the growth of the stands and indicate the trunk taper. To better solve these problems, we modified the previous experimental or empirical dry-type equations with the help of the theory of sub-growth and dynamics.
