＂5.12＂汶川地震造成灾区尤其极重灾区严重的生态破坏。论文以都江堰市为例,利用遥感（RS）和地理信息系统（GIS）等手段对震害区土地利用/植被覆盖变化进行监测,对动态变化进行定量分析,得到都江堰市地震生态受损及灾后两年生态恢复信息,并结合DEM对变化信息进行空间分析,研究灾害发生、生态恢复与坡度的相关关系,从而为灾区生态环境的恢复重建和保障生态安全提供借鉴和依据。

The Wenehuan earthquake on May 12th, 2008 caused serious ecological damage to disaster area especially the very quake-hit area. In this paper, a case study concerned was conducted in Dujiangyan City. In the study, by means of Remote Sensing （RS） and geographic information system （GIS）, the change of land utilization and vegetation cover in the earthquake disaster area were monitored. The dynamic changes were analyzed quantitively to obtain the information of ecological loses and restoration after two years later. Combining DEM, the changing information was analyzed spatially to study the correlation between the disaster occurrence as well as ecological restoration and the hill slope, which provided reference and basis for restoration and reconstruction of ecological environment and ensuring the ecological safety for the disaster areas.
