Considering the water quality, the total wastewater discharged into the reservoir-reach amounts to 1.2 billion tons annually (Wang, 2002). TGP does not generate pollution itself but it will aggravate the pollution belts, because of higher water level and slower velocity. The Chinese government decided that all the industrial pollutants must be treated to reach the (official) discharge standards by 2000. A number of small enterprises that discharge heavy pollution, such as paper mills, have already closed down, and the central government will invest a large sum to build a series of large wastewater treatment plants in Chongqing City, Wanxian City, Fuling City and Yichang City. In addition, the catchment management, pre-impoundment clearing…show more content…
A program of artificial reproduction of endemic fish species has been performed for more than a decade. For plant species conservation, a program has been initiated recently to conserve three more endangered species, Rhamnus tzekweiensis, Buxus ichangensis, and Plantago erosa var. fengdouensis (Zhang, 2011). Consequently, the efforts have also been shifted to the preservation of regional ecosystems with consideration of typical vegetation types (e.g., evergreen forests) and rare and endangered species in the region. An ecosystem conservation network has been developed in the TGRR including Dalaoling (Yichuang City, Hubei Province), Longmuhe (Xinshan County, Hubei Province), Shiping (Fengdu County, Chongqing), and Wushan (Wushan County, Chongq- ing) (Zhang. 2011).
7 Conclusion
This paper takes the Three Gorges Dam Program as an example to introduce the process of EIA, emphasizing on the impact and mitigation these two phases during the allover management. Among several analysis methods, we focus on the Cost-Benefit Analysis (CBA) methods to evaluate the affects of the TGD on the environmental and ecological system.
Although people benefit from the TGD a lot, the negative impacts of the TGD also cannot be ignored and should be considered seriously and thoroughly, which include
