The effects of snow depth (30 cm, 50 cm, 100 cm) and snow duration (60 d, 90 d, 150 d) on soil N dynamics and microbial activity in situ were explored in the alpine belt of the eastern Tibetan Plateau.Deeper snow-cover (50 cm and 100 cm) reduced NH4+-N content, microbial biomass carbon and nitrogen,fungi count, and enzyme activities, whereas did not change net N mineralization.No differences in N pools in the soil, microbial biomass, microbial counts, and enzyme activity were found under the different duration of snow cover, showing that accumulation and release in soil N pools did not be significantly changed by earlier continuous snow cover.
