| Research Abstract |
Soil organic carbon stocks in forest soils derived from air-fall tephra deposits and debris avalanche deposits were studied to evaluate the recent soil carbon accumulation rate. The accumulation rates of soil derived from air-fall tephra deposits ranged from 0.01 to 0.05kgC m^<-2>y^<-1> and the rate of the soil derived from debris avalanche deposits ranged from 0.003 to 0.004kgC m^<-2>y^<-1>, respectively. The former rates were remarkably larger than the rates reviewed by Schlesinger(1990), which ranged from 0.001 to 0.01kgC m^<-2>y^<-1> at boreal, temperate and tropical forests. Difference of these accumulation rates between the soils was due to soil textures which strongly affected a plant invasion and forest regeneration ; the tephra deposits had finer soil texture than the debris avalanche deposits.
