| 摘 要： | 右江为丘陵山区河流.河道平面、剖面形态和径流过程具有山区河流特征,而水流流速与水面比降小具有平原河流特性；自然条件下受沿程河床节点控制,河床冲淤变化被限制在相邻两节点河段之间；那吉、鱼梁航运枢纽建成后,由于汛期两枢纽畅泄,两坝间河段将基本遵循自然条件下河床演变规律. |
| 关 键 词： | 枢纽 河道特性 河床演变 右江 |

| Abstract: | The Youjiang river is hill and mountain stream.Its plane,profile and flow process has the characteristics of mountain stream,but it also has characteristics of plain stream because of small flow velocity and slope water surface.Under natural conditions,riverbed evolution is refined between two nodal points in riverbed.Under the operation of the Naji and Yuliang hydro-junctions,owe to full outflow in the flood period,the reach still basically follows the evolution law under natural conditions. |
| Keywords: | hydro-junction riverbed characteristics bed evolution Youjiang river |
