摘要
在近 10a来地质灾害普查和重点详查的基础上 ,对浙西南山地进行了区域地质构造与地质灾害 (隐患 )点颁的相关研究。结果表明 ,构造活动可通过地貌、岩性蚀变、土壤发育和断层节理等间接或直接影响崩塌、滑坡和泥石流的形成。从而在其空间自然分布上 ,表现为大地构造线控制下的带状分布。
Based on the general survey and the key detailed survey of geological hzazards in recent ten years,we studied the relationships between regional geological structure and the distributing of geological hazards.The results showed that neotectonisms affect the forming of landslide,falling and debris flow directly or indirectly by meeans of topography and geomorphology,erosion degree of rock,soil development,faults and joints,As a result,the spatial distributions of geological hazards have zonal distribution along the discordogenic fault,vertical distribution under the effect of neotectionic movement and porphyritic distribution under the effect of volcano-tectonic.
