摘要
在对地区构造活动、地貌演变特征、河段的稳定性分析，以及现代河道断面变化特性分析的基础上，利用大量钻孔资料和河床淤积层年代测定资料，恢复了小浪底河段距今2360a古洪水期行洪断面，为古洪水流量演算提供了必要而可靠的依据。
Based on the analysis of regional tectonic movements, geomorphology evolution features, river stability, as well as rivercabs section develOPment characteristics, ancient flood trmsport sections in Xiaolangdi reach in 2 300 years ago are 'sumedby using a number Of drill hole log and river sedimentation layer age dating data, which provides necessary and reliablereference for ancient flood discharge estimation.
