摘要

The present study was focused on two forest types Quercus leucotrichophora (oak) and Pinus roxburghii (pine) in Garhwat Himalaya, for vegetation analysis and soil carbon stock along altitudinal gradient and soil depth. The soil carbon was assessed ineach forest type by collecting soil samples from three different altitudes and depths. In both the forest types, soil carbon has positive relation with leaf litter production, density and basal cover of the forests which decreased significantly with increasing altitude and soil depth. The results indicate that a change in vegetation type and a shift of vegetation belts as expected in most climate change scenario might have a profound impact on SOC in the Himalayas. Between the forests; oak forest soil has more capacity to sequester carbon compared to pine forest, therefore, to enhance carbon sequestration potential the existed forest should be maintained and promote more regeneration for high density and basal cover within oak forest and where oak is invading in pine forest to mitigate future carbon level.
