一、黄河北干流梯级电站建设的经济效益黄河北干流系指自内蒙托克托以下到陕西潼关这一河段,长约868Km。其中,托克托至禹门口河长为735Km;禹门口至潼关为133Km(禹潼段亦称小北干流)。托禹段河床比降约为1.0‰,托站年径流总量为237亿m~3,加上区间来水,到禹门口站增至341.8亿m~3。在黄河水电开发规划中,北干流有万家寨、碛口和龙门三大电站外尚有龙口、天桥、
First, the Yellow River north of the cascade hydropower station economic benefits The Yellow River north of the main flow from the Inner Mongolia Autonomous Region to the following Tongguan Shaanxi Province, about 868Km. Among them, Tuoketuo to Yumen mouth river length is 735Km; Yumenkou to Tongguan is 133Km (Yu Tong section also known as Xiaobei main stream). The ratio of river bed in Tuoyu section was about 1.0 ‰, and the total annual runoff in torpedo station was 23.7 billion m 3, with the increase of water inflow to Yumenkou Station to 34.18 billion m 3. In the planning of the Yellow River hydropower development, there are Wanjiazhai and Qiantan Ports and Longmen Power Stations in the north of the country. There are Longkou, flyover,
