| 摘 要： | 金沙江上游波罗水电站库区泥石流较发育，有不同类型泥石流沟130条。泥石流以暴雨沟谷型泥石流为主，多集中发育于岩性相对软弱的千枚岩、岩屑砂岩及板岩的相对宽谷段，多为黏性泥石流。流域内绝大部分泥石流处于衰退或停歇状态，现代活动泥石流规模不大，多发育于植被破坏较严重区域，对当地人民生命安全及波罗水电站水库的淤积等影响不大。

| Abstract: | 130 Debris flows are scattered over the Boluo hydropower station drainage basin. The debris flows are controlled by the strata and lithologic character, geological structure, neotectonism and climatic conditions and so on. The most of debris flows are formed in gulch by rainstorm, a small amount of debris flows are developed on slope by rainstorm, and some others by glacial action. The Debris flows concentrate in some relatively wide gulch consisting of relatively weak rock such as phyllite, detritus sandst... |
