| Research Abstract |
Three plots along vegetation development are conducted to demonstrate early stage of carbon accumulation on 11 years old volcanic ash deposits. Carbon amounts of vegetation, litter and soil were 132-4502gm^<-2>, 19-1067gm^<-2> and 212-1047gm^<-2>. Rates of carbon accumulation of vegetation were higher than those of soils because of undeveloped decomposition systems. Estimated carbon fluxes of soils corresponded to vegetation development. Formation of A horizon was observed in the most developed shrub stage vegetation.
