Abstract
This paper used PS-InSAR method to monitor the landslide along Qing river. Several typical landslides area were selected as the experimental areas. 61 ASAR data have been processed, which were acquired from 2003 to 2010. The obtained preliminary deformation rate map not only included the experimental areas, but also showed several new landslides areas. The results showed that the deformation rate distribute between −8.4 to 8.18 mm/y in typical landslides area. Meanwhile an new landslide area in ShuangGuMu was detected with the subsidence rate for 5.3mm/y. As for PS-InSAR results were not consistent with the traditional surveying results, this paper analyzed the possible reasons which affected the landslide monitoring in Qing river reservoir area.
