摘要/Abstract

Abstract: By investigating dead trees in4 ha permanent plots of Korean pine-deciduous mixed forest of Changbai Mountain, the tree mortality of Korean pine-deciduous mixed forest is low. It ranges from 0.3 tree·ha^-1·yr^-1 or 0.46 t·ha^-1·yr^-1 to 2.1 tree·ha^-1·yr^-1 or 1.23 t·ha^-1yr^-1. Wind is one of the major causes of tree death. The influence of disturbances (windfall, fire, insects, diseases, human activities, ect.) on Korean pine-deciduous mixed forest during past survey period is iimited. This forest ecosystem is in steady state.

Key words: Tree mortality, Korean pine-deciduous mixed forest, Changbai Mountain
