The annual and seasonal mean streamflows presented significant downward trend.

The long-term runoff series covered one natural and three human-induced periods divided by turning years.

The high, low, and median flow in natural period was higher than that in human-induced periods.

The relative contributions of climatic and anthropogenic impacts on the runoff changes were quantified.

In the human-induced periods, human activities were the main factor declining the streamflow.
