| Research Abstract |
I have investigated to understand the relationship between distribution of forest communities and soil environment in a foggy mountainous watershed. The remarkablefindings are as follows. (1) Fog was formed by condensing at the base of watershed and then transported to the ridge line by sea breeze. (2) In the natural Cryptomeria japonica forests distributed on ridge line, frequent fog event was one of the limiting factors in inhibiting the evaporation from the forest floor. (3) Fluctuating range of seasalt loadings in the forest floor on ridge line was smaller than those at lower altitude.
