龙羊峡水电站1987年汛后将以它巨大的水量和强大的电力开始服务于青、甘、宁、蒙晋、陕六省(区)经济建设,发挥它在黄河中、上游水利系统中和西北电力系统中的“龙头”作用,促进我国西北地区的经济发展,社会经济效益显著。分析认为,用建设该水电站的投资去建设火电站,是替代不了它的全部作用和效益的。 After the Longyangxia Hydropower Station in 1987, it will begin to serve the economic development of Qinghai, Gansu, Ning, Mengjin, and Shaanxi provinces (regions) with its huge amount of water and powerful electric power, and play its role in the middle and upper reaches of the Yellow River. The role of “leading” in the northwest power system promotes economic development in the northwestern region of China, with significant social and economic benefits. According to the analysis, the construction of a thermal power station using the investment in the hydropower station cannot replace its full role and benefits.
