摘要:

黄河宁蒙河段穿越腾格里沙漠、河东沙地、乌兰布和沙漠和库布齐沙漠,形成了沙漠包围河流的独特地貌景观。近50年来,由于气候变化和人类活动的影响,该河段水沙关系加剧恶化,河槽萎缩、加速形成“悬河”,已引起国家高度重视和科技界的广泛关注。本文主要从风沙对河道的淤积、河道演变和高含沙洪水的影响3个方面阐述了风沙对黄河宁蒙河段的影响,以期为该河段的“悬河”防治和区域生态保护提供依据。

关键词: 风沙, 淤积, 高含沙洪水, 河道演变

Abstract:

The Ningxia-Inner Mongolian Reach of the Yellow River passes through the Tengger Desert, Hedong Desert, Ulan Buh Desert and Kubuqi Desert, forming a unique landform landscape of river surrounded by desert. In the past 50 years, due to the impact of climate and human activities, the relationship between water and sediment in this reach has worsened, the channel has shrunk and accelerated the formation of “hanging river”, which has aroused great attention of the state and the scientific and technological community. In this paper, the effects of aeolian sand on the Ningxia-Inner Mongolian Reach of the Yellow River were discussed from three aspects of sediment siltation, river channel evolution and flood with high sediment content, in order to provide a basis for the prevention and control of "hanging river" and regional ecological protection in this reach.

Key words: aeolian sand, siltation, hyper-concentrated flow, evolution of river channel
