Abstract

Landslides are one of the major hazards in Taiwan, especially after typhoon and earthquake, to maintain the slope stability is the most important task after disaster; vegetation cover is the key factor of slope stability. Vegetative cover can contribute to improving the stability of steep slopes by reducing erosion and the its growing are usually controlled by climate, soil, water, topography and geology condition, the growing conditions indicated that vegetation growing condition may also reflect the landslides spatial characteristics. The landslides and vegetation restoration evaluation was implement by high resolution air-photo, SPOT-5 satellite image and air-borne LiDAR in this study. Landslides were identified by using air-photo in 2004 which before Long -Wang typhoon, the satellite image and LiDAR data were acquired for calculated vegetation restoration rate, two different source data were both taken in the same month in 2005.The LiDAR data are used for derived surface roughness data to obtain the vegetation growing. The vegetation restoration result shows different spatial distribution in landslide area, the vegetation cover near river bank are less than where in slope area, the growing rate also shows the same appearance. The steep slope appears with low vegetation restoration rate, it may have relations with high frequency of landslides and lower disturbed by human in this area.
