This paper studied the relationships of nutrient elements of litter,soil fauna and soil from six major forest types of Xiao Hinggan Mountains.It was revealed that both the average content of elements and the variance from litter,soil fauna and soil in different forest types were not the same.The variance analyses(ANOVA) of nutrient elements from earthworm,enchytraeidae,centipede and other soil fauna showed that K,Ca,Mg and Fe had an influence on the growth of soil faunas.The significant linear relationship of K,Na and Fe with litter,soil fauna and soil indicated that these elements were closely related with litter,soil fauna and soil.Furthermore,the nutrient elements in leaf litter and soil were closely related to the biomass,density,and group of soil fauna.The order of the average relevant coefficient was: group>biomass>density.
