摘　　要：河北省宽城县位于燕山山脉东段,属于地质灾害易发区,地形复杂,气候多变,尤其在强降雨和地震等极端自然条件下,崩塌、滑坡、泥石流等地质灾害频发。为有效减少灾害损失,为当地防灾减灾规划提供科学依据,并提出相应的防治对策。通过对宽城县区域的地质背景、地质构造和气象条件的综合分析,结合多次现场勘查及地质灾害数据,系统研究了崩塌、滑坡、泥石流和地面塌陷等地质灾害的发育特征、分布规律及防治措施。结果表明,研究区内共存在125处地质灾害隐患点,主要包括崩塌(75处)、泥石流(35处)、滑坡(12处)、地面塌陷(3处)。崩塌和泥石流为主要灾害类型,集中分布于宽城镇、龙须门镇、塌山乡等地。滑坡主要分布于龙须门镇及塌山乡的低山丘陵区,且以小型滑坡为主。泥石流灾害则以沟道型泥石流为主,分布于地形起伏较大的沟谷区域。地质灾害的分布与地形起伏、岩性脆弱带,以及人类活动密切相关。不仅有助于丰富宽城县地质灾害的理论认识,还对类似地质背景区的灾害防治提供了一定的参考。Located in the eastern part of Yanshan Mountain Range,Kuancheng Manchu Autonomous County,Hebei Province,is an area prone to geological disasters.The terrain is complex and the climate is changeable,especially under extreme natural conditions such as heavy rainfall and earthquake,Geological disasters such as collapse,landslide and debris flow occur frequently.To effectively reduce disaster losses and provide a scientific basis for local disaster prevention and reduction planning,as well as to propose corresponding prevention and control measures,this study conducts a comprehensive analysis of the geological background,geological structures,and meteorological conditions of Kuancheng Manchu Autonomous County.Combining multiple field surveys and geological hazard data,the study systematically investigates the developmental characteristics,distribution patterns,and prevention measures of geological hazards,including collapses,landslides,mudslides,and ground subsidence.The results indicate that there are a total of 125 geological hazard risk points in the study area,primarily consisting of collapses(75 points),mudslides(35 points),landslides(12 points),and ground subsidence(3 point).Collapses and mudslides are the main types of hazards,concentrated in areas such as Kuancheng Town,Longxumen Town,and Tashan Township.Landslides are mainly found in the low mountainous and hilly areas of Longxumen Town and Tashan Township,predominantly as small-scale landslides.Mudslide hazards are primarily of the channel-type,distributed in the undulating terrain of valleys.The distribution of geological hazards is closely related to topographic undulations,weak rock formations,and human activities.This research not only enriches the theoretical understanding of geological hazards in Kuancheng Manchu Autonomous County but also provides a reference for disaster prevention and control in similar geological environments.
