Outline of Final Research Achievements |
This study aims to clarify the relationships between geo-surface processes on the sub-alpine slopes and forest dynamics of the subalpine coniferous forests. On the sub-alpine slopes, the surface flow from rain and snowpack often occur. Soil creep by the diurnal freeze-thaw cycles on autumn are also important as slope surface processes. In addition, glide of snow cover is estimated to be act to slope surface. On the other hands, first-year seedlings establish on the forest floor and surroundings until late autumn. First-year seedlings do not receive impact from the surface flow, and they stay alive until late autumn. The first-year seedlings are estimated to be receive impact from the soil creep and glide of snow cover.
