利用旺业甸林场固定标准地林木树高和胸径的调查数据，分别比较了平均实验形数公式法、平均实验形数标准木法和一元材积表法计算林分蓄积量和林分蓄积组成的计算结果。结果表明：3种方法计算的蓄积量中，任意两者之间存在线性相关关系；测算混交林树种组成系数不一致的，对优势树种（优势树种相同时，对低于5％的树种）的蓄积系数差值分类后进行符号检验，3种方法的蓄积组成计算结果在0.05水平下差异不显著。因此，平均实验形数法可以用于林分蓄积和蓄积组成的估测。对林农或家庭林场而言，平均实验形数公式法的实用性更强。

Based on the survey data of permanent sample plots at Wangyedian Forest Farm in Chifeng,the results of the stand volumes and species compositions were compared,which were calculated with three methods including the average experimental form factor (AEFF )Formula method,the AEFF and Mean Tree method,and One-Way Volume Table method,and linear relationships were found among the three different stand volume figures.In mixed stands,the inconsistent results of species composition were not significantly different at the 0.05 level with the sign test based on the classifications according to the coef-ficient difference of the dominant tree species(if they were the same,species less than 5%used).So,the average experimental form factors could be used to measure stand volume and species composition.To for-est farmers or family forest farms,the AEFF Formula method might be more useful than the others.
