In this study, we calculated the difference quantity of the DSM of before defoliation, while defoliation, and after defoliation using time series airborne laser scanner, and we tried to estimate the stratification in deciduous broadleaved forest by grasp of the growth and the covering situation of subtree layer, shrub layer, and herb layer from the amount of change of DSM. The target area of this study was set to
Zelkova serrata forest and cherry forest (
Prunus yedoensis etc.) in Tama Forest Science Garden. As a result, it was able to be divided 4 stratification types that deciduous broadleaved tree layer in which the understory vegetation does not develop, deciduous broadleaved tree layer in which shrub layer and herb layer develop, deciduous broadleaved tree layer in which subtree layer and shrub of evergreen broadleaved tree develop, and evergreen broadleaved tree layer (
Quercus glauca mainly) .
