ABSTRACT- The effects of timber harvesting on regeneration characteristics of Picea jezoensis and Abies nephrolepis were studied in Broadleaved-Korean Pine Mixed forest on north slope of Changbai Mountain ( longitude 127°6′ to 128°55′, latitude 41°20′ to 42°28′), China. Timber harvesting study plots was in Broadleaved-Korean Pine Mixed forest in Baihe Forest Bureau (industrial forestry enterprises) and natural study plots (as control) located adjacent Forest Ecosystem Station in Changbai Mountain. Our results showed that Volume of CWD (Coarse woody debris: fallen logs; cut stump ; snags ) and coverage of CWD in natural stand were greater than those in timber harvesting stand; Timber harvesting in Broadleaved-Korean Pine Mixed forest on the north slope of Changbai Mountain leads to a significant reduction of Picea jezoensis seedlings, and no significant change in Abies nephrolepis seedlings. Timber harvesting in Broadleaved-Korean Pine Mixed forest on the north slope of Changbai Mountain result in Picea jezoensis seedling density because of the reduction in CWD.
Key words: Picea jezoensis , Abies nephrolepis , Coarse woody debris, timber harvesting
