Resumo
The construction of cascade reservoirs has significantly changed the structure and function of river ecosystems. This study takes the maqu-xiaochuan section of the upper Yellow River basin as the research object. Based on the historical runoff and sediment data, water quality data, vegetation remote sensing data and field sampling data, the statistical analysis (trend test and continuity analysis, multiple regression residuals), SWAT model, hydrochemical analysis and other methods are used to elucidate the impacts of the construction of single reservoirs, double reservoirs, and cascade reservoirs on the hydrological processes and vegetation, and finally to assess the comprehensive impacts of cascade hydropower development on the hydrological processes and vegetation by constructing a comprehensive evaluation system of the hydrological processes and vegetation.
