对杉木人工林的３个生长性状—断面积、胸径和材积进行了典型相关分析，结果表明：断面积性状与材积性状的相关主要是由断面积平均生长量和材积连年生长量的相关引起的；断面积性状与胸径性状的相关主要是由断面积平均生长量、断面积连年生长量和胸径平均生长量、胸径连年生长量的相关引起的；材积性状与胸径性状的相关主要是由材积、材积连年生长量和胸径平均生长量、胸径连年生长量的相关引起的。
The results showed that the correlation between the cross-sectional area and the volume traits was mainly caused by the correlation between the average growth area of cross-sectional area and the annual growth volume of the plantation The relationship between the cross-sectional area and the DBH traits was mainly caused by the correlation between the average growth area of cross-sectional area, the annual growth of cross-sectional area, the average growth of DBH and annual growth of DBH. The correlation of DBH and DBH was mainly caused by volume, Annual volume of volume growth and average diameter at breast height, DBH caused by the amount of annual growth.
