Abstract:This paper presents the results of analysis on the height,d.b.h.andvolume increment of 99 korean pine trees and has found out the conclusionof its growth In Yichun Forest Area,Heilungjiang Province. In the natural stands of korean pine on Ⅱ Ⅲ Ⅳ site classes the maximumannual height growth of these stands in the age of 69,65,and 51 years old,are 0.31,0.28 and 0.23m respectively.The maximum diameterincrements ofthese stands in the age of 100,92 and 93 years old,are 0.44,0.41 and 0.36cm,respectively.The maximum annual volume increments appear in the age of170—180 years old. consequently,We have to pay more attention in managing,korean pinestands during the young stage,say,before 50 years old.
