林木生长率计算在我国常采用的方法有普莱斯勒(Presler)公式和施耐德(shcneidei)公式两种。普莱斯勒公式计算生长率的精度较高,但是计算比较麻烦;施耐德公式计算十分简单,但需要测定树冠长度和它占树高的百分比,以及根据树高生长状况来确定系数K值,实际应用也不方便,主 Tree growth rate calculation in our country commonly used methods are two kinds of formula (Presler) and Schneider (shcneidei) formula. The accuracy of the growth rate calculated by the Priceler’s formula is relatively high, but the calculation is troublesome. The calculation of the Schneider formula is very simple, but the crown length and its percentage of tree height need to be determined, and the value of the coefficient K is determined according to the growth of the tree height. Application is not convenient, the main
