龙羊峡和刘家峡两水库是位于黄河上游干流区的两座大型水库。这两座水库以发电为主,兼顾防洪和灌溉。两大水库投入运行后,为黄河上游地区的经济发展发挥了巨大作用。为了使水库产生更大的经济效益,更有效地利用水资源,就必须对水库进行科学、合理的调度。及时并具有一定精度的长期预报,是作好水库调度的重要依据。青海省电力局 Longyangxia and Liujiaxia two reservoirs are located in the upper reaches of the Yellow River two major reservoirs. The two reservoirs are mainly electricity generation, both flood control and irrigation. After the two major reservoirs have been put into operation, they have played a significant role in the economic development of the upper reaches of the Yellow River. In order to make the reservoir produce more economic benefits and make more efficient use of water resources, it is necessary to carry out scientific and rational dispatching of reservoirs. Timely and with a certain degree of accuracy of long-term forecast, reservoir scheduling is an important basis. Qinghai Provincial Electric Power Bureau
