To understand the spatial pattern of hill slides created by Wenchuan Earthquake and its impacts on giant panda habitat, vegetation and panda habitat before and after the earthquake was analyzed based on remote sensing and GIS modeling in Dujiangyan region. Results showed that 12,862hm2 of hill slides were created after this earthquake in this region, and 78.64% of these were in Longxihongkou nature reserve. Most of hill slides were distributed in mountains with the elevation between 1400-2400m above sea level and slope between 20-55°. About 21.63% of giant panda habitat was damaged by earthquake, which mainly occurred in elevation between 2200-3000m. The giant panda habitat was serious fragmented after earthquake, and the number of habitat patches was 7.7 times of that before earthquake. In Longxihongkou nature reserve, 32.15% of giant panda habitat was seriously damaged, while the damage of habitat outside reserve was moderate with the loss ratio of 9.83%. To conserve habitats for giant panda in this region, tourism inside the giant panda habitat should be forbidden in the process of restoration and re-construction.Key Words: Wenchuan Earthquake; giant panda; habitat loss; Dujiangyan region
