The litterfall, accumulation of soil organic matter and soil respiration were measured at different parts of a slope from the bottom to the ridge in an evergreen oak forest at Nara, central Japan, where the climax vegetation was preserved. The density of the trees and total basal area became greater toward the top of the slope, but the height and biomass of the trees were greater near the valley than on the ridge. The soil moisture content increased toward the bottom of the slope. There were no significant differences in soil temperature among the sites. The accumulation of surface litter (A_0) layer and total carbon in mineral soil increased toward the ridge, while the rates of litterfall and soil respiration decreased. It was shown that the decomposition rates of organic matter in A_0 layer and mineral soil decreased toward the top of the slope based on a simple compartment model.
