摘　　要：该文研究甘肃省电尕镇孕灾地质条件对泥石流的影响。电尕镇地形复杂,泥石流频发,对当地居民构成严重威胁。研究分析地形地貌、地层岩性、降水、地表水、冻融作用和人类工程活动等因素对泥石流形成与发展的影响。发现沟床坡度、沟岸山坡倾斜度和流域面积等地形条件,以及软硬相间的岩石构成和强烈风化作用为泥石流提供物质基础。降水、地表水和人类活动等因素触发了泥石流的发生。基于此,提出加强预警系统、实施工程治理、生物治理与生态保护以及加强宣传教育与居民参与等防治措施。这些措施将为电尕镇居民创造更加安全的生活环境,并为其他地区泥石流灾害研究提供借鉴。In this paper,the impact of disaster-inducing geological conditions on debris flow in Dianga Town,Gansu Province was studied.Dianga Town has complex terrain and frequent mudslides,posing a serious threat to local residents.The influence of factors such as topography,stratum lithology,precipitation,surface water,freeze-thaw action and human engineering activities on the formation and development of debris flow was studied and analyzed.It was found that topographical conditions such as ditch bed slope,ditch bank slope slope and basin area,as well as the soft and hard rock composition and strong weathering provided the material basis for debris flow.Factors such as precipitation,surface water and human activities triggered the occurrence of mudslides.Based on this,prevention and control measures such as strengthening early warning systems,implementing engineering governance,biological governance and ecological protection,and strengthening publicity,education and residents'participation are proposed.These measures will create a safer living environment for residents in Dianga Town and provide reference for research on debris flow disasters in other areas.
