Study on the Decomposition Rate of Xiaoxing'anling Broad-Leaved Korean pine Forest Litter

Korean pine forest,Pinus koraiensis,Pinus koraiensis,Pinus koraiensis forest clear-cutting litter burned the four forest types were buried decomposition test by mesh bag buried method.The litter decomposition rate and change the dynamic was studied.At the same time,the progress of decomposition of litter decomposition model for simulating prediction.The results showed that four type of forest litter studies have shown temporal process of weight loss rate increased,to the end of the experiment(396d),the final dry matter remaining rate of litter from small to large order was clear-cut,burned area,the original forest,artificial forest.Stage of decomposition rate performance of the broad-leaved secondary forest(Clear-cut and prescribed burning)as the main building species than the original Korean pine forest and artificial pure Korean pine forest.Decomposition of 95% need about 8.7 years of Pinus koraiensis litter.While the secondary forest decomposition 95% need about 4.3 years.Different forest types in the decomposition velocity and time difference.
