【摘要】 黔西北矿产资源丰富，是省内重要工业基地。该区位处云贵高原东缘，山高谷深。滑坡、崩塌、泥石流时有发生。影响开发建设。通过遥感解译和野外验证共发现滑坡、崩塌、泥石流等地质灾害２３６０处。主要分布在赫章一威宁金钟一线东南。受多种环境因素综合控制。切割剧烈的地形，陆源碎屑岩或玄武岩分布区，软硬岩层叠覆的地层结构，平缓的招皱构造以及断裂构造发育地段，都是容易发生滑坡、崩塌、泥石流的敏感部位。文中还对古滑坡、高速滑坡、潜在滑坡和地裂缝发展趋势、斜坡变形破坏的时间效应作了讨论，并对滑坡、崩塌、泥石流作了分区评价。更多还原

【Abstract】 Geological hazards such as landslide,rockpall and mud-rock flow,frequently attack the northwestern area of Guizhou-an important industry base,since this area is geographically situated on the eastern margin of the YunnanGuiZhou Plateau with intensively dissected topography.The interpretation of remote sensingimages, in combination with field examination, demonstrates that these incidental hazards are mostly in the places of 2, 360 southeast of the Hezhang-Weining’s Jinzhong line, which are influenced by complex geological environments. The areas sensitive to landslide, rockfall and mud-rock flow are nearly concentrated on the places where terrigenous elastic rocks, basalt, strata with interbeds of weakness and hardness in structure, gentle folds and faults.are well developed and strongly dissected topography are common.In addition to the trends of ancient landslide, high-speed landslided latent landslide, and geofracture, the time effect of destructive deformation of slopes are disscussed in the paper, regional evaluation for landslides rock fall, and mud-rockflows is also given.更多还原
