摘　　要：受“8·8”九寨沟地震影响,沙坝沟小流域内诱发新增大量山体崩塌、滑坡等次生地质灾害,松散物源量急剧增加,极大加剧了泥石流灾害的发生,对沟口聚居区及旅游设施等构成严重威胁。通过分析沙坝沟小流域震后地质灾害发育基本特征,分析研究主沟泥石流形成特征、灾害史及发展趋势,按照地震灾后恢复重建规划,提出了结合地方发展规划的防治方案,实施工程治理、监测预警、应急避险场所、生态恢复为主,与农村基础设施建设、旅游开发等结合的综合措施,保护了流域及危险区人们生命财产安全,为小流域地质灾害的防治提供可借鉴。Debris flow in the Shaba Gully induced by the Jiuzhaigou Earthquake on Aug.8,2017 seriously threat to the Mizoguchi residents and tourist facilities security.This paper has a discussion on characteristics,disaster history and development trend of the debris flow and makes suggestion on comprehensive control including engineering management,monitoring and early warning,emergency rescue,ecological restoration,rural infrastructure construction and tourism development.
