【摘要】 为了推进遥感技术在我国滑坡堰塞湖抢险救灾工作中的应用,对遥感技术在西藏易贡巨型滑坡堰塞湖、帕里河滑坡堰塞湖、汶川"5.12"地震滑坡堰塞湖处置中的应用情况进行了分析。在堰塞湖的监测中,采用遥感技术可直接或间接得到堰塞湖的回水长度、水面面积、积水深度空间分布、蓄水量和堰塞湖坝体或滑坡体的长度、宽度、高度、堆积体土石方量等信息,为抢险救灾工作提供重要的科技支撑。更多还原

【Abstract】 In order to advance the application level of remote sensing technology in the landslide dammed lake rescue and relief work in China,what and how has the remote sensing technology been used in the Tibet Yigong giant landslide dammed lake,Parry River landslide dammed lake,Wenchuan "5·12" earthquake landslide dammed had been analyzed.The results showed that:through remote sensing technology,the length of the backwater,backwater area,water depth,the spatial distribution of water storage capacity and the length of the barrier lake dam or landslide width,height,and the accumulation can been obtained directly or indirectly in the landslide dammed lake monitoring,which can provide important scientific support for the rescue and relief work.更多还原
