- Abstract
A field experiment was conducted using the litterbag method to quantify the contribution of soil fauna to litter mass loss of Salix paraplesia, Sabina saltuaria, Betula albosinensis and Abies faxoniana during different key periods of the decomposition process of the first year (from November 2011 to October 2012). The results showed that the mass loss rate showed S. paraplesia > B. albosinensis > A. faxoniana > S. saltuaria, and the rate in the growing season was greater than in the freeze-thaw season. The contribution rate of soil fauna to the mass decomposition displayed as S. saltuaria (26. 7%) > A. faxoniana (18. 8%) > B. albosinensis (15. 7%) > S. paraplesia (13. 2%), which was higher in the freeze-thaw season than in the growing season for litter of B. albosinensis and A. faxoniana while vice versa for litter of B. albosinensis and A. faxoniana. The contribution of soil fauna was mainly related to organic C, P and N/ P in the freeze-thaw season, while N, C/ N, lignin and lignin/ cellulose in the growing season.
