- Abstract
The supply capacity of freshwater ecosystem services (FES) is affected by climate change as a result of global temperature rising. However, previous studies have rarely focused on the interannual, seasonal, and periodic change characteristics of FES. We analyzed the effects of climate change on FES from 1960 to 2017 in the Guizhou Province in China. The water yield and soil retention in Guizhou at an annual scale exhibited a decreasing trend between 1960 and 2017, whereas the annual nutrient retention exhibited an increasing trend. The change trends of the three FES in spring and autumn were significantly different from the change trends in summer and winter. The change rate of the nutrient retention in all four seasons from 1960 to 2017 was opposite of that of the water yield and soil retention. The peak period of the water yield, soil retention, and nutrient retention at the annual scale occurred at 28a (i.e. 28 year), whereas differences were observed for the peak period of the three FES at the seasonal scale. The results of this study benefit the scientific management of the FES and contribute to reducing the negative effects of global climate warming.
