津波による沿岸林内樹木の被害に関する統計モデルの開発

抄録

A statistical analysis by using the filed data of damage of tree in a coastal forest due to a past tsunami was carried out, and the influence factor that contributed to damage of tree due to tsunami was extracted from a statistical analysis. And then, statistical models were developed by using the filed data. The statistical model for lodging rate explains the actual measurement value well by diameter of tree, root form, dn and tsunami inundation depth, The statistical model for destruction rate explains the actual measurement value well by root form, dn and tsunami inundation depth. In addition, actual probability of occurrence of tree damage and the probability of the present model used inundation depth from tsunami simulation were compared, and suitability of the present model was examined.
