摘要

根据对岷江上游主干支流松坪沟河谷地震诱发山地灾害的最新调研资料 ,在阐述 1933年 8月叠溪 7 5级地震在松坪沟河谷诱发的山地灾害类型及其特征基础上 ,总结分析其发育分布规律 ,叙述了诱发的崩塌、滑坡和碎屑流等山地灾害及对松坪沟造成的堰塞 ,形成一系列景观独特的堰塞湖 (海子 )。文章重点对公棚海子崩塌堰塞湖、下白蜡寨滑坡堰塞湖、上白蜡寨碎屑流堰塞湖等典型实例的形成演化机制进行剖析 ,最后 ,提出了恢复和保护松平沟生态环境的对策与建议。
On the basis of rencent research, the types and characters of Songping River earthquake mountain hazards are discussed in this paper. These mountain hazards were caused by the strong earthquake happening in Diexi of Min River on Aug.1933. The developmental and distributed regulation of earthquake mountain hazards is concluded and analyzed. At the same time, a battery of peculiar dammed lakes caused by the strong earthquake are depicted.The formation and evolution mechanism of classic example of dammed lakes, especially, the Gongpeng dammed lake caused by collapse、the down Bailazhai dammed lake caused by landslide、the upper Bailazhai dammed lake caused by debris flow, are mainly analyzed in this paper. At last,the eco-environment protective measures are suggested.
