摘　　要：密云区地质灾害隐患点共计2173处,是北京市地质灾害隐患点最多的地区。文章搜集整理2014—2023年密云区已发生的58起突发地质灾害调查资料,分析总结近10年密云区突发地质灾害多以威胁道路及居民点的小型滑移式和坠落式崩塌灾害为主。从斜坡类突发地质灾害时空分布规律和形成原因两个维度,分析得出地层岩性、地形地貌、地质构造3方面为引发密云区斜坡类突发地质灾害的内因,降雨及不合理的人类工程活动为引发灾害发生的外因。针对已有地质灾害防治措施,提出继续优化监测预警技术,完善群专结合监测,推进地质灾害综合治理,构建地质灾害防治科普体系的减灾策略,为突发地质灾害防治工作提供参考。There are a total of 2173 potential geological hazard points in Miyun District,which is the area with the most potential geological hazard points in Beijing.The article collects and organizes the investigation data of 58 sudden geological disasters that have occurred in Miyun District from 2014 to 2023,and analyzes and summarizes that in the past ten years,the sudden geological disasters in Miyun District are mainly small-scale sliding and falling avalanches that threaten the roads and settlements.From the two dimensions of spatial and temporal distribution patterns and formation causes of slope-type sudden-onset geohazards,it is analyzed that the three aspects of stratum lithology,topography and geological structure are the internal causes of slope-type sudden-onset geohazards in Miyun District,and rainfall and unreasonable human engineering activities are the external causes of the disasters.With regard to the existing measures for prevention and control of geological disasters,it is proposed to continue to optimize the monitoring and early warning technology,improve the monitoring of groups and specialists,promote the comprehensive management of geological disasters,and build the disaster reduction strategy of geological disaster prevention and control system of popularization of geological disaster prevention and control,so as to provide a reference for the prevention and control of sudden-onset geological disasters.
