| 摘 要： | 基于河流阶地高度和阶地形成年代数据,通过二者的线性拟合方法得到了渭河不同河段及其支流的下切速率,结果表明河流在陇西盆地的下切速率明显高于渭河盆地,可能反应了西秦岭北麓构造活动西高东低的特点。

| Abstract: | Based on the river terraces height and its age,the authors obtained the incision rates of Weihe river and its tributaries,which showed that Longxi basin was higher than Weihe basin,and it indicated the feature of west higher than east in the north flank of west Qinling. |
