长江三峡及其上游河流袭夺新认识

New Recognition of River Captures in Three Gorges and Its Upper Reaches

旨在揭示长江三峡及其上游存在的一系列河流袭夺事件 ,其中湖北新滩为跨两大流域间的总袭夺 ,其余皆为分袭夺 ,古金沙江、古雅砻江、古大渡河原属境外红河上游的三大支流 ,经解析反向阶地、风口和倒插支流等证据 ,得出在印度板块与欧亚板块碰撞及其后持续抬升作用下 ,促使上述事件的发生 ,结果导致长江延长 2倍多

A series of river captures in the Three Gorges and the upper reaches of the Yangtze River are revealed. Among the captures, Hubei Xintan is the major one crossing Yangtze River and Honghe River basins,and the rest the minor ones. While the ancient Jinsha River,Yalong River and Dadu River were branches of Honghe River.The analysis of such evidences as reverse terraces,wind gaps and inverse branches, leads to a conclusion that the collision of the Indian Plate with the Euro-Asian Plate and its subsequent gradual lifting force gave rise to the phenomena mentioned above,the extension of the Yangtze River by two-odd times and the remarkable change of environment of the basins.
