道真县地质灾害分布特征及易发性区划

Distribution Characteristics and Susceptibility Zoning of Geological Hazards in Daozhen County

针对道真县的地质灾害问题,通过野外地质调查以及资料的梳理和整理,详细分析了道真县地质灾害的类型、空间分布、发育特征等基本特征。同时,采用信息量模型对道真县地质灾害易发性进行了评价,将道真县划分为不同的地质灾害易发性区域。研究结果表明,道真县共发育地质灾害隐患点为158处,主要受坡度、坡型、岩组类型、地表、地下水等因素的控制作用,易发性区域主要分布在工作区的水系两岸,提供了科学的依据和参考,对于提高当地居民的生命财产安全和促进经济社会的可持续发展具有重要意义。

Focuses on the geological hazard issues in Daozhen County.Through field geological investigation and the organization and analysis of data,the basic characteristics of the types,spatial distribution,and developmental features of geological hazards in Daozhen County are analyzed in detail.Meanwhile,the information quantity model is employed to evaluate the susceptibility of geological hazards in Daozhen County and to divide it into different zones.The results show that there are 158 potential geological hazard points in Daozhen County,which are mainly controlled by factors such as slope gradient,slope type,lithology type,surface,and groundwater.The susceptible areas are mainly distributed on both sides of the water system in the work area.The study provides scientific basis and reference for the prevention and control of geological hazards and geological environmental planning in Daozhen County,which is of great significance for improving the safety of life and property of local residents and promoting the sustainable development of the economy and society.
