摘要

Taking multi-temporal high resolution satellite data as the RS information and DEM derived from Orbview as the geographical control, digital landslide technique has been adopted to study and monitor 2004-06-22 Landslide activities. Satellite image interpretation reveals that before landslide occurred the part of slope had already been the dangerous rocks before sliding, surrounding by fractures and nearly separating with slope, 2004-06-22 Landslide is considered as a high-speed slide activity of bedrock bedding, which is calculated as 63.7×104 m3 in volume by the use of RS+GIS. Satellite monitoring shows that each part of the landslide has not changed during 35 months from Sep., 2004 to Jul., 2007.
