A rough estimation of the technically developable volume and the economically developable volume for the Changjiang River Valley was drawn out on the basis of new data. According to the estimation, the developable water energy resources of the whole valley is 257 627.60 MW with an annual energy output of 1 195.142 billion kW·h - respectively amounting to 120.6% and 116.3% of the General Investigation result in 1980. The proportion of economically developable volume in the technically developable volume ranges the medium level in the world. According to the 3-step plan for the national economic and social development, the economic situation of our country will come up to the standard of medium-developed countries in the mid of the 21st century. Calculation reports from related departments show that the national electric power requirement in the Year 2050 will be 6 200 billion kW·h (basic scheme) ～11 600 billion kW·h (ideal scheme) while the electric power requirement of the South-west, Central and East areas of the nation within the Changjiang River Valley will amount to 44% ～ 50 %. In order to satisfy the electric power requirement of the national economic and social development, the development and utilization of the hydraulic energy in the Changjiang River Valley should be speeded up by stressing its strategic position and taking effective measures. The structure of the electric energy components of the three areas will be improved with the increasing proportion of the hydroelectricity. The hydroelectricity should be mainly developed in the South-west area; both the hydroelectric and fossil-fired power should be developed in the Central China; the fossil-fired power should be mainly developed in the combination of hydropower while nuclear power will be properly developed in the East China. In the Year 2050, the development of the economically developable hydraulic energy in the whole valley will be basically completed and the proportion of the hydropower in the electric energy components will be 40%.展开更多
