“分水岭迁移和河流袭夺” 理论存在许多错误。分水岭的发展是有方向的，它的移动方向决定于两侧内外营力总作用程度的对比。只是河流溯源侵蚀不能切穿分水岭。河流兼并可能是由高位河向下跨流域改道而成。

The theory of migration of divide and river capture has many mistakes. The develop-mental direction of the watershed is multiform and its migratory direction is decided by thecontrast of all action degree of internal and external agents on both sides of the watershed.Only headward erosion cannot cut through the watershed. Annexation between rivers may bemade when a high river changes its course by going downwards and across the valleys.
