摘　　要：分析了宁夏黄河干流不同河段的河床组成、河道平面形态、河床演变特性等基本特征,量化了不同河段综合稳定性指标。将宁夏黄河干流冲积性河道划分为分汊型(沙坡头坝下—仁存渡河段)、游荡型(头道墩—石嘴山河段)、过渡型(仁存渡—头道墩河段),并研究了自然因素和人为因素对河型形成的重要作用。Based on the study of river bed composition, river flat shape and fluvial process characteristics of different reaches of theYellow River in Ningxia, the quantify integrated stability index for different reaches is studied. The Yellow River is an alluvial river, and the reach in Ningxia is divided into braided river （from Shapotou dam to Rencundu） , wandering river （from Toudaodun to Shizuishan） , and transitional river （from Rencundu to Toudaodun）. Finally, the study focuses on the influences of natural and anthropogenic factors on the river pattern formation.
