Abstract:

The paper uses the approach of NDWI model to extract the water bodies of the Tangjiashan barrier lake from the multi-source satellite images of ALOS AVNIR-2 and CBERS-02B CCD and detects the changes of the barrier lake pre- and post-earthquake. The result shows that the river widen through Zhangping area increased from 92 m on Mar. 31, 2007 for per-earthquake to 420 m on May 16, 2008 and 474 m on May 18, 2008 for post-earthquake. And the area of barrier lake in the study area increased from an surface area of 0.6938 km2 on Mar. 31, 2007 for pre-earthquake to 1.2842 km2 on May 16, 2008 and 1.3658 km2 on May 18, 2008 for post-earthquake.
