为深入研究不同树种或不同立地条件下同一种树的立木生长特点,分析它们的胸径、树高、形数和材积等因子的变化规律以及生长过程,主要的方法是进行树干解析。这是目前被普遍采用并公认的一种比较准确可靠,简便易行的研究立木生长全过程的不可置疑的最完善的巧妙方法。至今也有五十多年的历史了。但是,我们认为:解析木各园盘高度的年令计算(各圆盘高度的年令=树木年令一
In order to further study the growth characteristics of standing trees of the same tree under different tree species or different habitats, the variation rules of their DBH, tree height, shape, volume and other factors as well as the growth process are analyzed. The main method is to analyze the tree trunk. This is currently widely accepted and recognized as a more accurate and reliable, simple and easy to conduct the whole process of standing wood growth of the most perfect and clever way. So far there are more than 50 years of history. However, we think: Calculate the annual calculation of the height of each garden disk (annual height of each disk = Year of the tree
