摘　　要：本文对非均匀卵石的河床组成、颗粒暴露度的分布特性进行了分析研究,在此基础上确定了计算床面,可为非均匀卵石起动及输移规律的研究提供参考。In this paper, the composition of river channel and the distribution charateristics of the exposing height of sediments are studied. Based on this research, the calculating river channel surface is defined. The research results can provide reference for the study of the law of threshold motion and transportation of gravel.
