| 摘 要： | 黄河下游郑州京广铁桥—兰考段河道穿行于华北平原济源—开封凹陷,南邻太康隆起。该河段为著名的地上悬河,属典型的游荡型河床,河流地质作用以强烈侧蚀南岸为特征。遥感、物探综合解译首次发现在河道南岸存在一东西向郑州—兰考区域性隐伏深大断裂带,该断裂带的发现,从河流地质作用特征与基底新构造活动关系方面解释了该段黄河发生、发展和演化机理,解释了河床“小尺度游荡,大尺度呈直线状延伸” 的河道地貌特征和“河流强烈侧蚀南岸”的河流地质作用特征,对黄河下游河道防洪、治理具有重要意义。 |
| 关 键 词： | 黄河 遥感 隐伏断层 河流侵蚀 |

| Abstract: | Characterized by strong erosion of the south river bank from the Jingguang railway bridge in Zhengzhou to Dongbatou in Lankao, the lower reach of the Yellow River, which is a hanging river in this part, runs along Jiyuan—Kaifeng rift, with Taikang uplift on the southern side. With the discovery of Zhengzhou—Lankao regional concealed fault between Jiyuan—Kaifeng rift and Taikang uplift based on the interpretation of remote sensing and geophysical exploration information, the following phenomena can be explained reasonably: How does the river come into being, develop and evolve? What causes the river to stretch straightly from Zhengzhou to Lankao in the EW direction in spite of the fact that the river bed shifts in the river channel? Why does the river erode the south bank most strongly? The discovery of the fault and the river erosion characteristics is of great significance in river improvement and flood prevention in the lower reach of the Yellow River. |
