摘要
1引言 森林衰亡是全球关注的林业问题,尤其在欧洲地区,大片森林死去,造成了巨大的经济损失。
By investigating dead trees in 4 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^(-1)yr^(-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.
