%X As a significant factor for maintaining river ecosystem function, ecological and environmental water requirement of rivers is a key issue of hydrological research. Based on real conditions of the middle Yellow River, a few methods (Montana method, minimum monthly mean discharge method, etc.) were adopted to calculate ecological and environmental water requirement of the river. The results show that in the middle Yellow River the environment water requirement is 47.356×108 m3, the water requirement for sediment delivery is 40.666×108 m3, and the water surface evaporation is 10.314×108 m3. Total tributary ecological and environmental water requirement from Kuye River, Wuding River, Fen River, Jing River, Beiluo River, Wei River, Yiluo River, and Qin River is respectively 2.071×108 m3, 3.393×108m3, 10.143×108 m3, 8.699×108 m3, 3.575×108 m3, 34.601×108 m3, 6.481×108 m3 and 2.505×108 m3. Due to the non-independence of the middle Yellow River, further ecological and environmental water requirement research is recommended.
