| Outline of Final Research Achievements |
In this study, we established a simulation model in order to evaluate influence of disturbance on forest dynamics under the frequent typhoon environment from 3 sub-models: frequency, damage and recovery. Parameters of the sub-models were determined using long-term monitoring data. We calculated the dynamics of main species in a lucidophyllous forest for 300 years with the model under the current typhoon frequency. Main species were classified into 3 types; slight increase, decrease and rapid increase. In the same way, we did under the more frequent typhoon condition. Although all groups decreased ratio of the population in contrast to current frequency, the speed of decrease differed with gropes. This suggests that changes of typhoon frequency would influence composition and dominance of species in lucidophyllous forests.
