摘要
在东川区县(市)地质灾害详细调查过程中,SPOT5高分辨率卫星遥感数据对泥石流灾害具有较好的解译效果。通过对泥石流SPOT5遥感影像特征进行研究,建立了东川区泥石流遥感解译标志,并对沟谷型泥石流和坡面型泥石流进行识别,共识别了沟谷型泥石流168条,坡面泥石流95处。
The high resolution satellite data of SPOT5 has better interpretation effect to the debris-flow hazards on the geological surveys of Dongchuan county. Based on the research of future of debris-flow in Dongchuan county, he interpretation indication of the debris flow was built up and the vale debris-flow and the sloping debris- flow were indentified. Totally 168 vale debris-flows and 95 sloping debris-flows were identified.
