Based on fission track analysis of Hungling Granite, combining with research of planation surfaces and terraces characteristics in field, the authors obtain data of uplift velocity and uplift height of Huangling Dome since 65 Ma. The research results reflect uplift history in this area has close relationship with formation and evolution of the Qinghai-Xizang Plateau, and also restrict formation time and process of the Yangtze Three Gorges, and prove the Three Gorges is a youth river valley. On the other hand, surface geological activities aroused by uplift of Huangling Dome will have some effects on the Three-Gorges Dam.
