#### Abstract

This study was conducted to investigate the growth patterns of Maackia amurensis growing in natural forest of Mt. Joongwang, Pyongchang-gun, Kangwon-Do, Korea. The 28 sample plots(30m$\times$30m) wee established to examine the vegetation and environmental conditions for M. amurensis forest. Stem analysis was performed on two sample trees of M. amurensis for each of the 5 plots situated at intervals of one hundred meters by altitude. The results obtained were as follows: ⑴ Height growth of M. amurensis increased with increasing age until 10 years, and then decreased thereafter, especially at altitude of 1,020m. ⑵ M. amurensis showed rapid early growth of height and volume, indicating high biomass production under favorable environment. This growth pattern is typical of pioneer species such as Cornus controversa and Betula costata. ⑶ The rotation age of natural M. amuensis forest was estimated at above 50 years, and especially at about 60 years in 840m above the sea level. ⑷ Growth of M. amurensis increased greatly at about 40 years when released from severe competitions.
