| Research Abstract |
Wind damage of coniferous plantation forests was studied in Japan. Wind conditions determined using an air flow simulation model and remote sensing measurement were integrated within a Geographic Information System(GIS). Based on the data set, the relationships between wind disturbances, wind speed and stand height were analyzed. The results indicate that higher wind speeds and greater stand heights increase the probability of wind disturbance plantation forests. Finally, we analyzed differences in wind hazard risk among harvesting strategies. This study demonstrated that it is possible to obtain spatial-temporal sustainable forest management strategies to improve the supply of timber on a regular, quantitative basis
