Abstract:
The study on the characteristics of runoff evolution can provide a scientific basis for the development of water resources plans and establishment of hydrological response mechanisms. In this study, the runoff evolution characteristics of Fuyang station were analyzed using M-K test and wavelet analysis based on the discharge data of Fuyang hydrometric station from 1956 to 2011, and the main factors influencing the runoff changes were analyzed from the perspective of climate change and human activities. The results showed that the runoff of Fuyang station of Shayinghe River decreased but the decreasing trend was not significant, not reaching the 95% significance level. An abrupt change occurred around 1966. There was a 13-year periodic variation and a 26-year periodic variation of the runoff, and the periodic evolution process was affected by human activities significantly. As for the driving factors, the contribution rate of human activities to runoff changes was more than 65%. The impact of climate change on runoff changes was relatively weak, and tended to turn from negative to positive.
