针对尼泊尔4·25Gorkha地震诱发山地灾害的现象,基于多源光学遥感数据,使用目视解译方法分析了震前和震后地物特征的变化,调查了Rasuwa区影响抗震救灾的公路沿线滑坡、堰塞湖的空间分布。结果表明:本次地震新形成的大型滑坡较少,大部分为中小型滑坡、浅层滑坡及碎屑流、崩塌和落石等灾害,并有堰塞湖。而在影像上能清晰识别的灾害点有15处,其中3处危害较大,分别为Langtang滑坡、Resuo滑坡和1处堰塞湖。Langtang滑坡造成了严重的破坏。

A few mountain hazards were induced by the Gorkha Earthquake of Nepal 4·25.In this paper,we investigated the landslide,Dammed Lake and so on along the road which effect the relief by using multiple sources of optical remote sensing images.We also analyzed the ground object changes before and after the earthquake by using visual interpretation method and investigated the distribution of mountains hazards in Rasuwa district.The results show that there is less newly formed large landslide.Most of hazards are small and medium landslides,shallow landslide,debris flows,avalanches,rockfall and Dammed Lake.On the image there are clearly identifiable 15hazards,in which three harmful,respectively Langtang landslide,Resuo landslides and one Dammed Lake.Langtang landslides caused severe damage.
