Figure 5
Analysis framework in this study. Water budget is determined by natural water yield and human disturbance, and it can be illustrated by regional streamflow change. The streamflow of the Yellow River has an overall decrease and several periods of sharp reduction in recent decades. The relationship between the coupled human-natural system and the water budget has been found. Note that the gradient fill of arrows represents the change of impact level, a light color means weaker effects while the darker color represents stronger effects.
