| Research Abstract |
The authors built the infiltration map which expresses the infiltration characteristic from the relationship between vegetation, geology and topography information. As a result, it was able to evaluate quantitatively the hydraulic properties of soil which vegetation tends to grow. The comparison of vegetation distribution showed that the permeable range of the slope which a Japanese cypress inhabits was wider than a Japanese cedar. Moreover, "Water Retentivity Index" which expresses quantitatively the important water holding property of the infiltration environment of a forest was defined. Thereby, it became clear that it is possible to evaluate the soundness of a forest.
