摘要
玉龙县位于青藏高原东南边缘横断山脉向云贵高原过渡的衔接地段,兼具横断山峡谷和滇西高原两单元地貌特征.近来年,地质灾害频繁,尤其是泥石流灾害.本文收集了雾露湾地质、气象和水文等资料,通过分析该沟的地形、物源和水源条件分析泥石流形成过程,雾露湾泥石流的成因机制为"暴雨"型,同时提出泥石流的治理措施.
Abstract
Yulong County is located at the junction of the Hengduan Mountains on the southeastern edge of the Qinghai-Tibet Plateauand the Yunnan-Guizhou Plateau,so thatit has the geomorphological characteristics of both the Hengduan Mountains Gorge and the Western Yunnan Plateau.Geological hazards,especially debris flow,have occurred frequently in recent years.Based on collection of the geological,meteorological and hydrological data of Wuluwan,the formation process of debris flow was investigated by the topography,material source and water source conditions analyses,indicating that the formation mechanism of Wuluwan debris flow is'rainstorm'type.The control measures of this debris flow were put forward.
