利用遥感手段进行地质灾害编图的初步讨论--以印江县为例

摘要

利用正向地貌、逆向地貌，岩层倾角等值线，软质岩类区、硬质岩类区、软硬叠覆带分别代表控制地质灾害发育的地貌因素、构造因素、地层因素等编制区域地质灾害图是一种新的尝试。它在一定程度上较准确地反映出地质灾害发育的内在规律。遥感手段的应用使得编图更加经济、准确、快捷、方便。%A new test that takes advantage of normal geomorphology, reversed geomorphology, isogram of bedded tilt angle, soft petrographic region, hard petrographic region, soft and hard belt of superposition to separately represent geomorphologic factor, structural factor, strata factor and so on for drawing geological cataclysm map, which accurately reflect the inner regular of geological cataclysm development in some degree. Applications of remote technique make the compilation more economic, precise, quick and easy.
