The data of this data set comes from collection and numerical simulation. The inflow of Longyang Gorge, longliu section and Liulan section are from the measured flow results of Tangnaihai, Minhe, Xiangtang, Hongqi, Zheqiao and other hydrological stations in the upper reaches of the Yellow River, the temperature and the date of closure and opening of the river at Shizuishan station, Bayan Gaole station, Sanhu Hekou station, Baotou Station and Toudaoguai station are from the measured temperature and the date of closure and opening of the river at Shizuishan station, Bayan Gaole station, Sanhu Hekou station, Baotou Station and Toudaoguai station in the upper reaches of the Yellow River, All stations are national basic hydrological stations, and the test is carried out in strict accordance with the specification requirements. The data are compiled and released, and the data are reliable. The data of withdrawal water from xiaheyan to Toudaoguai are from the water use plans of all provinces (regions) in the available water consumption distribution and non flood season water regulation plan of the Yellow River issued by the Yellow River Water Conservancy Commission of the Ministry of water resources over the years. The minimum and maximum discharge indicators of the reservoir are the range of ice control indicators proposed in this study. The initial water levels of Longyang Gorge, Liujia gorge and Haibo Bay come from the measured water levels of each reservoir. The water level of Haibo bay at the end of November 20, the water level of Haibo bay at the end of December 31, the maximum diversion flow of the ice diversion area in Haiba section, the maximum diversion flow of the ice diversion area in Sanbao section, the population size, and the number of iterations are free to set parameters for the calculation of the self-developed optimal operation model for the joint ice prevention of the reservoirs in the upper Yellow River and the ice diversion area. The output data of the models such as the water level process of each reservoir, the outflow flow process, the flow process of the main hydrological station from Lanzhou to Toudaoguai, and the water storage increment process of the river channel are simulated and calculated by using the self-developed optimal operation model of the joint anti icing of the reservoirs in the upper reaches of the Yellow River and the sub icing area.

  Longyang Gorge storage, longliu section, Liulan section are from the measured flow results of Tangnaihai, Minhe, Xiangtang, Hongqi, Zheqiao and other hydrological stations in the upper reaches of the Yellow River, Shizuishan station, Bayan Gaole station, sanhuhekou station, Baotou Station, Toudaoguai station temperature and the date of closure and opening of the river, the diversion water data from xiaheyan to Toudaoguai section, and the initial water levels of Longyang Gorge, Liujiaxia and Haibowan are extracted. The minimum and maximum discharge indexes of the reservoir are obtained on the basis of the research results, combined with the analysis of different boundary conditions of the river.

  The model output data of the water level process of each reservoir, the outflow flow process, the flow process of the main hydrological station from Lanzhou to Toudaoguai, and the water storage increment process of the river channel are simulated by the self-developed optimal operation model of the combined anti icing of the reservoirs in the upper reaches of the yellow River and the sub icing area. The objective function of the model is to minimize the maximum flow at Toudaoguai section, maximize the total power generation of the upstream reservoir group during the ice flood season, and maximize the sum of the water storage of longliu reservoir at the end of March. The model is solved by using the non dominated sorting genetic algorithm with elite strategy (nsga- Ⅱ). On the basis of the multi-objective Pareto non inferior solution set, 2000 non inferior solutions are optimized respectively, and the sample optimal solution is obtained as the recommended optimal operation result.
