摘　　要：通过对程海半海子村泥石流野外调查,并结合工程勘测技术手段,分析了区域地质环境情况,阐明了泥石流形成条件以及动力学参数特征。结果表明:半海子村泥石流沟地质环境条件恶劣,泥石流爆发频次高且对程海生态环境造成严重影响。研究成果可为程海流域水土保持以及地区防灾减灾提供依据。Through the field investigation of debris flow in Half Hazi Village,Chenghai,and combined with the technical means of engineering survey,the regional geological environment was analysed,and the conditions for the formation of the debris flow as well as the characteristics of the kinetic parameters were elucidated.The results show that the geological conditions of the mudslide ditch in Half Hazi Village are poor,and the frequency of mudslide outbreaks is high and has a serious impact on the ecological environment of Chenghai.The results of the study can provide a basis for soil and water conservation and disaster prevention and mitigation in Chenghai basin.
