Storage dynamics of fallen trees in the broad leaved and Korean pine mixed forest
阔叶红松林倒木贮量的变化规律

A study was carried out the storage dynamics of fallen trees in the broad leaved and Korean pine mixed forest in the Changbai Mountains,Jilin Province,The fallen trees storage dynamics includes the existing fallen trees and the annual input in the mixed forest.The existing storage of fallen trees was 16.25 t/hm 2 in the initial stage,then the storage reduced,after 100 years,85% of the dry weight was decomposed and only a few left after 300 years.The average annual input of fallen trees was 0.6 t/hm 2,it increased with the lapse of time and became 31.0 t/hm 2 after 200 years.It would maintain this amount until the climax community was over.The total storage of fallen trees increased in the early stage.In pace with the decomposition of fallen trees,the storage was identical with the annual input of fallen trees,and finally it would be stable.
