森林生长量的调查,无论在森林资源清查中或是森林经理中,都具有重要意义。在国内测树学文献中,曾介绍了测定树木和林分生长量的各种方法,诸如利用中央断面积求积式或区分求积式测定伐倒木生长量;利用直径生长率与材积生长率的关系求算立木材积生长量;通过树干解析测定树木生长量。林分生长量的测定方法则有:标准木法;材积表法;材积差 The investigation of forest growth is of great importance both in forest inventory and in forest managers. In the domestic tree-finding literature, various methods for determining the growth of trees and stands have been introduced, such as the use of quadratically plotted quadratically or differentiated quadrats to measure the growth of cut downwoods; the use of diameter growth rate and volume growth rate The relationship between the calculation of standing volume of timber growth; determination of tree growth through tree trunks. Stand growth determination methods are: standard wood method; Volume Table method; Volume difference
