Effects of vegetation restoration on runoff and its components in the mountainous Haihe River Basin
Study region: Two typical mountainous Haihe River Basins: The Xiaojue Basin and the Yehe River Basin Study focuses: The mountainous Haihe River Basin has suffered from a water crisis duo to large-scale restoration. Quantifying the hydrological impacts of vegetation restoration is necessary for local water management. In this study, we used the Soil and Water Assessment Tool (SWAT) hydrological model, in combination with two vegetation restoration scenarios, to analyze the effects of vegetation restoration on runoff and its runoff components (surface runoff, baseflow, and total runoff) New hydrological insights for the region: Our results indicated a general decrease in surface runoff and an increase in baseflow as a result of vegetation restoration. At the seasonal timescale, total runoff and surface runoff decreases mainly concentrated in the flood season, and slightly increased in the non-flood season, and baseflow showed the opposite trend during the flood-season in the Xiaojue and Yehe River Basin. The magnitude of change in runoff components in the Yehe River Basin was higher than that in the Xiaojue Basin, and the Yehe River Basin has a larger water yield capability. This study advances our knowledge on the way in which vegetation affects runoff and offers recommendations for water resources management
