headward erosion

made the headward erosion of the Yellow River stronger,meanwhile the redistribution of water resource made it down erosion power stronger.

5万a前后的共和运动使得黄河溯源侵蚀加剧,水资源的重新分配,导致黄河切蚀能力加强,并于距今1。

The headward erosion is being cut down by the brooklets along the joints.

有的是沿着节理发育的深切溪沟溯源侵蚀 ,其源头已经伸入到了河流阶地之中 ,使阶地面遭受切割 ;有的是阶地面被数条溪沟分割之后 ,胜似滑坡而非滑坡 ;有的是残积坡积层沿着阶地前缘斜坡的部分均质岩层层面顺层滑落 。
