Abstract: The study on soil animal biomass in larch plantation with different ages shows that in different stands, soil macroanimals occupy 41.6~64.0% of the total, middle-small size animals 24.4 ~ 39.0%, and hygrocolous animals 8.9~25%. Among them, earthworm is the maximum, nematode is the medium, and enchytraeidae is the minimum. Soil animal biomass is positively related to the litter, plant coverage, soil pH, soil moisture content and soil organic matter.
