摘要
以1992年实测淮河中游纵剖面为基础,分析了淮河中游洪河口至浮山河段纵剖面形态,研究了1951～2005年54年来沿程纵剖面变化规律.除局部河段外,淮河中游深泓以下切为主,近期下切速度加快,文中系统分析了深泓下切成因.
Based on the longitudinal profile of mid-reach of Huaihe River measured in 1992,the morphology of longitudinal profile of the mid-reach from Honghekou to Fushan of the river is analyzed herein and the then the changing tendency of the longitudinal profile along the river from 1951 to 2005 is studied.The study shows that the talweg of the mid-reach of the river is mainly undercutted excepted local reaches and the undercutting rate is accelerated recently,and the causation of the talweg undercutting is systematically analyzed as well.
