Abstract

Climate and vegetation are important components of a changing environment that have synergistic effects on surface runoff. To date, few researchers have included the synergistic effects of changes in climate and vegetation in runoff simulation studies. In this study, a water-heat balance model based on the Budyko hypothesis was established, and an empirical formula for estimating model parameters based on the Normalized Difference Vegetation Index was proposed. This Normalized Difference Vegetation Index-climate relationship model allowed the synergistic effects of changes in climate and vegetation on runoff trends to be analyzed. The model was tested in the Fen River Basin, China. The results showed that the annual runoff would be 15.4%–39.5% (between 2020 and 2100) higher under two climate change scenarios than in the baseline period (2006–2015). Climate-driven change in the vegetation cover accounted for 8.0%–19.6% of the total variation in the runoff. The change in the vegetation cover inhibited the increase in runoff. To improve the accuracy of models and avoid overestimates, synergistic changes in vegetation and climate should be included in model simulations.
