Abstract: The study was conducted on the basis of 274 permanent plots of the spruce-fir conifer and broadleaf mixed forests in Changbai Mountain,and each tree in the plots was measured.From 1987 to now,the diameters at breast heights were investigated every two years.The relationship between basal areas at breast height per hectare and stand volume per hectare was analyzed by using different kinds of models,and the mixed basal area at breast height per hectare was obtained.Simultaneously,the basal areas a... More
