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 coefficient 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 forest farmers or family forest farms,the AEFF Formula method might be more useful than the others.
