Flood process in a forest was estimated based on the examination of forest structures at Kusu River in Kyushu,Japan.Tree age,tree size and tree species were measured for analyzing forest structures.Forest structure showed two types of flood processes.One type was the process due to damage by a debris flow and the other type was the process due to intensity and frequency of floods in a long term.The former was expressed as variation of forest damage along a debris flow,which stopped with disintegration.The latter was expressed as variation of recovery stage of forest structure.These results lead to propose a forest dynamics model based on recovery stage with frequency and intensity for estimation of flood process.

通过对日本九州Kusu河流域森林结构的考察，估计了森林的洪水过程。测量了树龄、树高和树种，分析了森林结构。森林结构表现出两种类型的洪水过程。一种类型是由于泥石流造成的破坏，另一种类型是由于长期洪水的强度和频率造成的过程。前者表示为森林破坏沿泥石流的变化，泥石流随崩解而停止。后者表现为森林结构恢复阶段的变化。基于上述结果，提出了一种基于恢复阶段、频率和强度的森林动态模型，用于洪水过程的估计。
