摘要

莫拉克颱風侵襲台灣造成極大的影響，運用福衛二號影像進行崩塌地判釋，將判釋成果與降雨資料比對，發現主要崩塌發生於累積雨量大於800公厘的區域；將判釋成果按水系與水庫集水區來看，發現在莫拉克颱風所新增的崩塌率，就水系的主集水區來看約在5%以下，而就水庫集水區來看新增崩塌率亦在1.68%以下。

Taiwan was seriously affected by the Typhoon Morakot. It was found the landslides occurred mainly in those areas with rainfall accumulation greater than 800 mm by comparing the landslide data recognized from Formosat-II imagery with the corresponding rainfall data, the landslide ratio increment caused by Typhoon Morakot was less than 5% in main stream catchment and was less than 1.68% in reservoir catchment.
