We applied dendrochronology method to study disturbance history during past 200 years and growth response of Pinus koraiensis in a broadleaf Korean pine-spruce and fir forest ecotone. The community composition was consisted of pioneer species Larix olgensis,mid-tolerant P. koraiensis,and shade-tolerant Picea jezoensis and Abies nephrolepis,and the growth releases and age structure analyses suggested frequent small-scale disturbances and two medium-scale disturbance events. The radial growth of P. koraiensis was significantly and positively correlated with July temperature of current year,and had no relationship with precipitation. Climate change may directly and indirectly affect tree regeneration and growth in the ecotone, and influence community composition and structure. Therefore,the community dynamics should consider both impacts including direct and indirect climate change.
