The Three Gorges Reservoir will bring about broad and profound impacts on ecosystems and the environment, covering various factors and vast areas and lasting a long time. The isslles involved are complicatedly interpenetrated and have both positive and negative aspects. But view the general conclusions as a whole, the environment of the Three Gorges Reservoir is in keeping with the demands of sustainability. On the questions, the author presents in this paper, based on the principles of the sustainable development, some indexes that can be used to evaluate the environmental sustainability of the Reservoir, and assesses briefly the environmental sustainability of the Reservoir. The research result indicated that, of the ecoligical and environmental factors to be affected by the construction of the Reservoir, the resettlement is a relatively sensitive and restrictive one.
