Changes in the water and sand fluxes of the Yellow River are not only related to the environmental management along the Yellow River basin, but also have far-reaching impacts on climate change and people's lives. In order to deeply understand the dynamic change law of water and sand flux, this paper adopts a multiple linear regression model to analyse the influencing factors of water and sand flux in the Yellow River. Among them, multiple regression equations were established with water level and flow rate as independent variables, and the results of the model showed that water level is the main factor influencing the sand content. Meanwhile, the article also calculated the total flow and sand discharge in the last 6 years, which provided basic data for the follow-up study. The results show that there are obvious seasonal and interannual variations in the water and sand fluxes of the Yellow River, and there is a complex correlation relationship with meteorological factors. Possible trends of the Yellow River water and sand fluxes are derived through model prediction and simulation, which provide a scientific basis for the development of sustainable water resources management strategies and help to ensure the sustainable use of water resources in the Yellow River Basin.
