| Outline of Final Research Achievements |
The purpose of this research is to clarify the influences of forested Peridotite basin on the water quality, material flow and seashore vegetation. Investigations were conducted by the method of comparing the Peridotite basin and the other than Peridotite basin.
In the Peridotite basin, the quantitative ratio of run-off was high and run down through the surface of slope. And amount of DOC liquate out was large.Organic(DOC)-inorganic(Fe) complex were flow out from the bottom of O- layer of the soil, under the coniferous forest, mainly in autumn season. Fewer SS(Suspended Sediment ) were run-off and ratio of fallen leaves run-off was high. It was concluded that water environment and vegetation at the seashore area were conserved by forested Peridotite basin. But, on the other side, following situation was grasped that Kelp vegetation areas are decreasing by the effects of environmental deteriorations.
