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、新构造运动影响下的垂直分布和火山构造赋予的斑块状分布规律
Based on the census of geologic calamities and the detailed survey in the recent 10 years, the related research on regional geological tectonics and geological disasters (hidden dangers) was conducted on the southwestern Zhejiang mountain. The results show that the tectonic activities can directly or directly affect the formation of landslides, landslides and debris flows through landforms, lithological alteration, soil development and fault joints. Therefore, in its natural distribution of space, it shows the zonal distribution under the control of tectonic line, the vertical distribution under the influence of neotectonic movement and the patchy distribution pattern given by volcanic tectonics
