主　　题：The Yellow River water, Isotope, Hydrological cycle 

摘      要：Based on the isotope analysis result of water samples in the 18 sections of the Yellow River, the variation of δ 18 O and δD have been analyzed. From near the source to the entrance to the sea, the Yellow River has a general trend that the ratios of the stable isotope increase progressively; The main factors affecting the isotopes in the river water are mixing of external water bodies,evaporation and others; In the river segment between Lanzhou and Baotou and in lower reaches, the extent of the evaporation effect on the isotope fractionation from the river water surface is limited but the evaporation from the irrigated river water and the return flow is one of the main factors affecting the isotopes in river water.
