Abstract
In this study, we examined the possibility of classifying representative tree species based on color change and defoliation transition during the leaf falling period in Tama Forest Science Garden (Tokyo Prefecture), where the forest type similar to that of Satoyama is preserved. We used the time-series aerial color photographs jointly with airborne laser scanner data. The tree species were classified according to the change in color tone of the aerial color photographs taken in spring and autumn. Further, the pattern of change in fallen leaves and the stand structure of deciduous broad-leaved trees were also observed on the basis of the change in height (crown) sensed by the airborne laser scanner during the leaf falling period so as to classify the species of representative trees in the mixed forest. As a result, the tree species in this area could be classified into Castanopsis cuspdata var. Sieboldii, Quercus glauca, Cryptomeria japonica D.Don, Chamaecyparis obtusa Endl., Zelkova serrata, Quercus serrata, etc.
