Abstract: In the original forest,three typical forest types are selected as Ledum Larch,Grass Larch and Rhododendron Larch and the different species nutrient content was determined. Based on the existing material combined with the research object and the greater hinggan sing-an larch and three birch wood decadent hierarchy standards are formulated. The results show that different types of different tree species in organic C,all the K,all the Na and Ca,Mg,of content with the wood constantly decomposition are but no significant changes in law; All the N content is in a trend of increase. The all the P remained relatively stable.For three types of wood in larch fall,the nutrient contents are compared,and Organic C,all the K,and all the P percentage content of leaves are the Rhododendron Larch > Grass Larch > Ledum Larch leaves pine; All the N,all the Na and Ca percentage content of Rhododendron Larch > Ledum Larch > Grass Larch; Mg percentage content of the Grass Larch﹥Rhododendron Larch > Ledum Larch.

Key words: Larix gemelini, original forest, fallen tree, nutrient content
