In order to investigate the change of mineral cycling with the part of slope, the parmanent experimental plots were set in a deciduous broad-leaved forest at Sanbe Forest of Shimane University.
1. The composition of tree species in forest standing on one slope changed with the water condition along the slope. Main vegetation changed from mesic species to xeric species as Cornus controversa HEMSL., Caroinus tschonoskii MAXIM., Quercus serrata THUNB., Pinus densiflora Sieb．et Zucc., Ilex macropoda Miq. along the slope.
2. There were tendencies for the mean diameter and tree height of plots to become smaller with ascending slope.
3. There were tendencies for the tree density and basal area of plots to become greater with ascending slope.
4. The amounts of organic matter accumulated on A_0 layer increased, and the amounts of carbon and introgen in mineral soils decreased with ascending slope.
