The ecological and environmental problems of the Three Gorges Reservoir Area have different effects on its ecological security. This paper analyses the relative carrying capacity of resources of the Three Gorges ecological-economic region in Chongqing and draw a conclusion as the following: the regions over loading of population accounts for 37.4% of the total population. The conflict between human and environmental systems of the region becomes severe. Aiming at the ecological security problems of Three Gorges Reservoir Area, the authors put forward the countermeasures such as: to establish the mechanism of ecological compensation along with a three-dimensional running-mode in this region; to build a ecological security prediction system and green GDP accounting system; to advocate production and management under the ecological security mode; to set up county- and city-level management system; to make different purviews and responsibilities clear for the different ecological drainage areas; to lead the public to produce safely and to decrease ecological disasters with science and technology.
