【摘要】 四川卧龙国家级自然保护区受到茂县-汶川断裂的控制及2008年汶川5月12日8级地震的严重影响,山体岩石破碎,地质灾害具有较高的易发性。卧龙保护区地质灾害类型主要有崩塌、滑坡、泥石流和不稳定斜坡。2013年4月有关机构编制了卧龙保护区159个实测地质灾害点数据资料,其中崩塌80处、泥石流42处、不稳定斜坡20处、滑坡17处。地质灾害风险分析表明卧龙保护区地质灾害威胁人数6 727人次,威胁财产达26 195万元人民币。地质灾害主要分布在皮条河沿岸,从河流上游的邓生沟到河流下游的水界牌地质灾害情况逐渐加重。皮条河-渔子溪可以划分为3个灾害程度不同的区域:邓生沟-核桃坪中度地质灾害区、正和水电站-耿达镇重度地灾区,渔子溪极重度地灾区。更多还原

【Abstract】 Wolong National Nature Reserve was severely affected by Mao County-Wenchuan fracture control and Wenchuan earthquake on May 12,2008. The main types of its geological disasters were collapses,landslides,mudslides,and unstable slopes. The agency compiled the measured data about 159 geological disaster spots of Wolong Reserve in April 2013,including 17 landslides,80 collapses,42 mudslides,and 20 unstable slopes. The geological disaster risk analysis showed that 6 727 people and 261. 95 million yuan property were threatened by the geological disasters. The geological disasters were mainly distributed along the Pitiao River shore,and became graolually serious from Dengsheng Ditch to Water Dividing Board. At the same time,few recommendations were put forward about the disaster prevention and control based on geological disasters characteristics.更多还原
