摘要:
泥石流侵蚀输沙量不仅反映了泥石流形成区地理环境特征和泥石流搬运能力，也反映了泥石流规模和泥石流搬运泥沙等固体物质在泥石流堆积区造成的严重程度。本文以泥石流灾害典型区长江上游蒋家沟流域1965—2007年的泥石观测资料为基础，利用功率谱方法分析了该流域泥石流侵蚀输沙量的周期变化，发现其存在5~7 a的显著震荡周期，这种周期的形成主要与该流域5～6 a的年降水量周期震荡以及受降水控制和影响的滑坡活动与坡面侵蚀影响相关。
Abstract:
The sediment transport not only reflects the geography environment of the formative region of debris flow and the transport capacity but also indicates the accumulating extent of solid matter in accumulation zone of debris flow and the magnitude of debris flow scale. In this paper, based on the observation data for debris flow from 1965 to 2007 in Jiangjiagou watershed, Yunnan Province, the periodicity of transporting sediment in debris flow was analyzed by using the power spectral method. Results showed that transporting sediment of debris flow present the periodicity from 5 years to 7 years. The reason maybe lied in rainfall periodicity from 5 years to 6 years in this basin and the sloping erosion and landslide caused by rainfall.
