The Three Gorges Project (TGP) on the Yangtze River is the largest water resources project in the world, major environmental benefits will be produced on the middle and lower basins of the Yangtze Rive, such as effectively control the flood and providing huge quantity of clean electrical energy. Whereas the main negative impact will be exerted at the upper reaches. Such as the large amount of farmland inundated and large number of population relocated. This paper introduces briefly the largest eco-environmental monitoring network in the world-- eco-environmental monitoring system of the Three Gorges Project (TGP) in Yangtze River. Based on analysis the eco-environmental monitoring data in latest years, some main effects are summarized as follows: it affects on local climate; affects on temperature and quality of water; influences on plant and animal resources in the reservoir area; influences on aquatic life; affects on earthquake and landslide; affects on human health; influences on natural scenery and historical relics; influences on the middle and lower reaches of the Yangtze; influences on the Yangtze Estuary and its adjacent sea areas. But all these effects are not serious. By a long-term monitoring and studying on eco-environment of the Yangtze River and the TGP’s reservoir area, it gives a forecast of what may happen of the TGP’s eco-environment in the future. That is to say, Favorable effects are mainly in the middle reach of the Yangtze; adverse effects are mainly in the reservoir area. But some latent effects are still not clear at present. According to the main negative impacts on the eco-environment, some countermeasures are suggested for the implementation of the TGP. It should work out a resettlement scheme for the Three Gorges Project; it is urgently necessary to take effective measure to carry out extensive soil conservation work in the upper reach and the reservoir area; it should establish certain natural preserves and national parks to protect important natural resources and historical relics, and proclaim relevant regulations; it should strengthen environmental protection and carry out development-oriented resettlement; in the design and operation of the Three Gorges Reservoir full consideration should be taken for the ecological and environmental demands below the dam; Continued effort should be made for some ecological and environmental problems needing further clarification.
