Abstract

In this study, the AA. collected soil samples from different wetlands in the discontinuous permafrost zone of the Xiao Xing'an Mountains, northeastern China. Permafrost was only present in the bogs and fens in this zone. Soil C concentrations were significantly correlated with total N concentrations and bulk density. Wetland type, soil depth, and incidence of fire affected soil C and total N concentrations, suggesting that vegetation changes in wetlands could alter the soil C and nutrient sequestration processes under future global warming scenarios. However, the soil C storage and total N storage were not significantly difference in the upper soil layer for the wetlands types. The vegetation changing of bogs and fens would increase the depth of the permafrost active layer
