Abstract: The litter decomposition is mainly from July to August in the frigid region of Northeastern China.The relationship between seasonal variation of soil litter and 19 ecological factors were studied by grey relation analysis.The primary and secondary factor influencing the decomposition of Litter were founded as Actinomycete, Cellulase, Moisture and Temperature.Then the grey model was established as:dX1 (1)/dt-0.06680663X1(1)(t)=-0.5764525X2(1)(t)+ 5.15529X3(1)(t)-0.2459588X4)(1)(t)-1.142576X5(1)(t).

Key words: spruce-fir forest, seedling and sapling, spatial distribution pattern, spatial heterogeneity, geostatistics, Changbai Mountains.
