雅砻江二滩水电站库区泥石流十分活跃,在库区内,沟谷型泥石流沟100条.库首左岸的金龙沟,多次暴发过泥石流,用金龙沟泥石流活动特征与短历时雨强的资料,经计算分析后,得到了库区泥石流活动规律、流域环境条件与雨强之间的关系式,并给出了金龙沟暴发泥石流的降水指数3600,有助于泥右流预报.  相似文献

通过对金沙江向家坝库区长约150km范围内的55条泥石流沟发育状况统计显示。自库首至库尾。泥石流沟的数目、发育密度及规模均呈逐渐增强趋势。同时泥石流沟的流域面积、主沟长度及纵坡平均坡降均存在明显的分形特征,它们与沟道数目之间有良好的非线性关系,并在一定程度上揭示了这些泥石流沟谷形态演变的非均匀性和自相似性。  相似文献

九甸峡水库蓄水后库区地质环境发生较大程度上的改变,地质灾害发育。通过对库区的多次实地调查,分析了地质灾害的发育、分布特性及其影响因素,系统地分析了库区地质灾害的主要类型。结果表明:河流对库区地质灾害的分布具有重要影响,地质灾害点的分布基本位于距离库岸3 km范围内,约有50%位于1 km范围内,随着与库岸的距离增加,表现为递减趋势;地质灾害的分布与地貌有密切的关系,大多数地质灾害发生在高程2 200~2 500 m,尤其是坡度30°~50°的范围内;地质灾害在流域内分布范围广、灾害点多、具有带状分布特征,主要沿库区沿岸发生,多呈线性分布;不同的岸坡结构控制着地质灾害的发育、分布,地质灾害的类型、发育分布也与坡体结构、岩土体性质密切相关;库区滑坡和泥石流主要类型分为3类,分析了灾害形成机制,为库区地质灾害的防治提供可靠依据。  相似文献

解明恩  程建刚  范菠 《山地学报》2005,23(5):571-578
根据云南滑坡泥石流灾害资料,分析了其形成环境与分布特征,给出了典型降水滑坡泥石流灾害事件,研究了滑坡泥石流灾害与气象环境的关系。云南滑坡泥石流灾害主要出现在盛夏7~8月,主要影响天气系统有切变线、冷锋、西风槽、西南涡、孟加拉湾风暴、南海西行台风和两高辐合区。诱发滑坡泥石流灾害的前期降水类型有3种,即暴雨型,中~大雨型和连阴雨型。得出了云南滑坡泥石流发生的区域临界雨量指标,提出了滑坡泥石流灾害的气象监测预警方法。  相似文献

Desertification is a global phenomenon that affects about two billion people. It occurs in arid zones where the annual precipitation is below 400 mm, partic- ularly in the marginal areas of the world's largest deserts. It is a result of water and wind erosion, over- grazing, global warm-ing, improper soil cultivation, and increased pressure ot population growth, and it causes degradation of soil and natural and agricultural vegetation. The direct result is less food for people and livestock, which influences pop- ulation and animal husbandry fluctuations. Despite ef- forts to combat and reduce desertification, the affected areas are annually increasing.  相似文献
