摘要
在长期观测资料的基础上,据泥石流沟床临界纵坡的研究值,估算泥石流固体物质总补给量;年均补给量可由多年泥石流运动观测值确定。两者可供泥石流发展趋势分析和制定防治方案时参考。
The solid materials in the catchment is the total supplied volume of debris flow solid materials when the gradiend and slope of valley are closing to their critical value. The total supplied volume of debris flow solid material in Jiangjia Ravine Catchment is 750Mm3. There is 2. 76Mm3 solid materials of debris flow coming from the catchment every yrar according to obsevational data of debris flow runoff in many yrars. The result shows that the forecast to the debris flow in Jiangjia Ravine will last for 270a±.
