摘要
"5.12"汶川地震后,四川灾区发生了大量的滑坡和泥石流。滑坡不仅威胁到人们的生命财产,而且为泥石流的发生提供了大量的物源。以安县桑枣镇研究区为例,进行了滑坡遥感163处,面积为146.86×104m2,并在erdas软件的支持下,将解译结果叠放在遥感三维影像上,运用遥感三维可视化飞行技术宏观分析研究区地形地貌,地质灾害分布情况,为地方政府制定决策方案提供一些信息。
The Wenchuan Ms 8.0 Earthquake resumed in great amount of landsides and debris flows which created great damage to people＇s life and property. Exemplified by Sangzao Town, Anxian County, this paper deals with geomorphology, distribution of geological hazards based on remote sensing image interpretation and 3D visualization of 163 landslides with an area of 146.86×10^4m^2, providing some information for prevention and cure of the landsides and debris flows.
