摘要
Shifang City as the study area, dynamic changes in land during 2007～2008 has been analyzed by using GIS technology and integration of multi-source space data. Studies have shown that when the study area is not affected by the external force, the pattern of land use and landscape is relatively stable, but under the secondary disasters due to earthquake and the external force, the deformation of landscape of woodland, open forest land, grassland is larger, and urban land, rural residential areas and farmland is also affected by the earthquake. The ideas and researching methods based on remote sensing technology for analysis of dynamic changes of land-use have been applied to the study area, and the results will be the important reference of ecological environment evaluation in the disaster area.
