摘要
五峰县主要地质灾害类型为滑坡、崩塌危岩体、不稳定斜坡、岩溶塌陷、泥石流,尤其以滑坡和崩塌地质灾害为主要发育形式。调查与统计数据表明,地质灾害发育在时间和空间上受到地形地貌、地层岩性、地质构造、大气降雨、人类工程活动等因素的控制。在探讨五峰县地质灾害发育类型特征的基础上,运用统计的方法分析各类地质灾害的控制因素,讨论防治对策,为地质灾害的防灾区划提供参考。
In Wufeng county,the primary geological disaster types are landslide,rock fall,unstable slope,karst collapse and debris flow,especially the landslide and rock fall are the primary development types.The investigation and statistical data demonstrate that the development of geological disaster in time and space are controlled by the factors as geographic and geomorphic conditions,formation lithology,geologic structure,rainfall,human engineering activities and so on.The occurrence of geological disaster threats people＇s life and property security.In order to avoid heavy losses,the authors utilize the statistical method to analyze each geological disaster controlling factors in this article,and discuss the prevention strategy,based on the primary research of geological disaster development types and characteristic in Wufeng county.It has great important significance in geological disaster prevention.
