摘要

In Taiwan, landslide usually appears in orogenic mountain belts after earthquake and typhoon events. In this paper, we aim to assess the temporal trajectory of Normalized Difference Vegetation Index (NDVI) time series by using SPOT images to carry out the landslide mapping from 1999 to 2009 in Nantou County, Central Taiwan. By quantifying the temporal change of NDVI index, we can identify the extent, location, and timing of the landslide. Preliminary results reveal different temporal patterns of landslide activities through potential disturbances of vegetation recovery index refer to earthquakes with magnitude Mw over 6 and typhoons with precipitation higher than 200mm/day. We expect that our proposed method can contribute to the generation of multitemporal landslide inventory more efficiently.
