Over the past ten years since the resettlement project started in 1993, 709,200 people or 62.76% have been resettled. Thanks to the principle of "resettlement by development," the Chinese government has paid full attention to protecting the property right, the right to employment, the right to residence and the rights and interests of disadvantaged groups. As a result, the resettlement project has given a powerful push to the overall economic and social progress and sustainable development.展开更多

We found that： ① In dam area of the reservoir, gravity effect resulted from water load increase is the most significant, maximum gravity change is 200×10^-8 m/s^2, but this effect is limited in amplitude and range. Gravity change can be observed about 5 km offshore. The gravity change caused by ground water level change is regional; and the impact of precipitation on it should not be neglected. ② At head area of the reservoir, the maximum gravity change is near Xiangxi. Monitoring the variation of gravity field and further study should continue in the future.展开更多

Practice shows that any large State planned project will bring prosperity to the local economy. The Gezhouba Dam Project in Yichang has provided the first opportunity for the city’s development During the first stage of the Gezhouba project from 1971 to 1980, the annual average progressive growth rate of fixed assets investment and展开更多
