摘　　要：甘肃省作为黄土高原的重要部分,地质灾害高发,对当地民众生命财产安全构成严重威胁。该文以甘南地区的迭部县电尕镇为例,进行一系列地质灾害隐患判识和高精度调查,深化地质灾害形成机理和发育规律认识。研究发现,迭部县电尕镇的滑坡主要分为黄土滑坡和残坡积层滑坡,崩塌分为基岩崩塌和土质崩塌,泥石流形成受地质、地形和降水条件共同影响。致灾模式包括滑坡、崩塌和泥石流致灾模式。为防治地质灾害,采取工程措施和非工程措施,如建设支挡结构、修建排导设施、构建监测网络和普及防灾知识等。这些措施为迭部镇地质灾害的防治管理提供基础依据和技术支撑。As an important belt of the Loess Plateau,Gansu Province has a high incidence of geological disasters,posing a serious threat to the safety of local people's lives and property.Taking Dianga Town,Diebu County in Gannan Prefecture as an example,this paper carried out a series of geological disaster hidden dangers identification and high-precision investigations,deepening the understanding of the formation mechanism and development laws of geological disasters.Research found that the landslides in Dianga Town,Diebu County are mainly divided into loess landslides and residual slope laminated landslides.Collapse is divided into foundation rock collapse and soil collapse.The formation of debris flows is affected by geology,topography and precipitation conditions.Disaster-causing models include landslides,collapses and mudslides.In order to prevent and control geological disasters,engineering and non-engineering measures have been taken,such as building support structures,building drainage facilities,building monitoring networks,and popularizing disaster prevention knowledge.These measures provide basic basis and technical support for the prevention and management of geological disasters in Diebu Town.
