摘　　要：长苞铁杉天然林生长缓慢,在22a时,胸径平均生长量达最大值。树高前8a生长较快,以后逐年下降。材积生长逐年增加。经营过程中,可在15～20a间进行适当间伐。The natural Tsuga longibracteata forest grows slowly,the average dbh growth reaches the top value at the age of 22.The tree height grows relatively quickly before the age of 8,and decreases with the years after the age of 8.The volume growth increases year by year.During the managemental course, the suitable intermediate cutting may be conducted during the ages of 15～20.
