摘　　要：5.12汶川地震激发了龙门山风景区崩塌、滑坡、泥石流、堰塞湖等链状次生山地灾害。通过应急调查发现,该区已有堰塞湖5处,危害性崩塌、滑坡6处,已成灾泥石流沟1条,潜在泥石流沟11条,根据各处灾害的主要特征,确定堰塞湖的危险程度,提出山地灾害处理建议。5 · 12 Wenchuan earthquakes widely triggered the mountain hazards as collapse, landslide, debris flow and barrier lake in Longmenshan Mountains Scenic Spot. In the emergency survey it is found that there have been 5 barrier lakes, 6 hazardous collapse and landslides, 1 debris-flow site and 11 possible debris-flow sites. According to the main features of kinds of hazards, the dangerous degree of the barrier lakes is identified and the mitigation measures are suggested.
