鄂西远安县地质灾害发育特征与形成条件分析
Analysis on the development characteristics and forma-tion conditions of geological hazards in Yuan'an county, Western Hubei
摘要
Abstract
Based on the detailed investigation and results of data statistics of geological hazards in Yuan'an Coun-ty,we sort out the development characteristics of the quantity,type and scale of geohazards in the study area.At the same time,the spatial and temporal distribution characteristics and formation conditions were systematicly an-alyzed.Through investigation,it is evident that geological hazards in this county break out frequently,occur sud-denly, and have serious harm and strong concealment. The distribution of the disaster is closely related to the landform.The landslide disaster is mainly distributed in the hilly area of the eastern part of the county.The col-lapse disaster is mainly distributed in the middle and low mountain areas in the western part of the county.The geological disasters in the central area are not well developed. Most of the geological disasters occur during the rainy season.The internal factors affecting the formation of the geological disasters include topography,lithology and geological structure while external factors include rainfall and human activity in this region.关键词
