摘要
中更新世中后期，涪江支流通口河强烈的溯源侵蚀，切穿了与安昌河（涪江的另一支流）的分水岭．首先袭夺安昌河上游段（湔江）的支流都坝河，随之整个湔江水均注入通口河，安昌河成断头河．河流袭夺地貌特征十分显著，不仅对该地区经济发展产生影响，而且为科研、教学提供好场所，又是地学旅游的好去处。
In the middle and later stage of the Medial Pleistoncene epoch,the strong erosion of trace to the source of Tongkouhe River, a tributary of the Fujiang River, removed the watershed between Tongkouhe River and Anchanghe River,the other tributary of the Fujiang River. Dubahe River, a trebutary of the Jianjiang River located in the upper reaches of Anchanghe River,was firstly captured, secondly the whole water of the Jianjiang River flowed into Tongkouhe River, so Anchanghe River was becoming a river without riverhead. The characteristics of the configuration of the earth's surface is rery obvious due to the river capture. It affected not only the economy's development in thiis region, but also supply a good place for the scientific research,education and tourism.
