Besides the ecological and environmental problems, what other negative impacts are there in the Three Gorges Project?

The negative impact of the Three Gorges Project is not only an ecological environment problem, but also a human impact.

After the impoundment of the reservoir, the canyon feeling of the Three Gorges will be weakened, and the surrounding area of the Three Gorges was the intersection of Ba culture and Chu culture in ancient times. More than 200 cultural relics/kloc-0 have been found in the flooded area of the reservoir. Since 1992, the cultural relics department has started to carry out rescue excavation, and it is expected to complete rescue protection before water storage in 2009.

In addition, the government has set up special projects and allocated special funds for the protection of national key cultural relics protection units and other important ancient architectural relics.

Environmental effect

The environmental impact of the Three Gorges Project comes from reservoir pollution. Sewage and domestic garbage discharged by towns and tourists on both sides of the Three Gorges are directly discharged into the Yangtze River without treatment.

After water storage, because the water flow is still, pollutants can't flow down in time and accumulate in the reservoir, which causes water quality deterioration and garbage floating, and may cause infectious diseases. Some towns collect domestic water from other sources, and at the same time, a large number of immigrants reclaim wasteland, which also aggravates water pollution and causes soil erosion.

In this regard, the local government is vigorously building sewage treatment plants and landfills to solve the pollution problem. If it is found that the pollution is too serious, it is also possible to build a dam to increase the flow to realize water exchange.

The Three Gorges Project will have an impact on the surrounding ecology. Because of the dam, fish can't pass through the Three Gorges normally, and their living habits and heredity will change. After the impoundment of the Three Gorges Reservoir, more than 560 species of rare terrestrial plants will be submerged, but most of them are also distributed above the submerged line. Only Selaginella laxiflora and Clematis chinensis are completely below the submerged line and have been transplanted.
