Short summary
We quantitatively isolated the relative contributions that human activities and climate variability made to decadal streamflow changes in Jinghe basin by three methods. We concluded that the three methods were in good agreement in terms of the dominant contributor, i.e., human activities played a more important role in the streamflow decrease than climate changes. We qualitatively discussed the errors and uncertainties, and will make an attempt for further research on quantitative discussions.
