In order to make sustainable management decisions for multiple ecosystem services, it is important to clarify the relationship between ecosystem service tradeoffs and synergies. In this study, the spatiotemporal variations of soil conservation, water yield, carbon sequestration were analyzed using land use and land cover(LULC), soil types, meteorology, and DEM datasets in the Qinghai-Tibet Plateau Ecological barrier area of China. In addition, we identified hot spots for three ecosystem services supplies, and explored the tradeoff and synergistic among three ecosystem services. The results showed that:(1)the soil conservation, water yield and carbon storage all showed a decreasing trend from southeast to northwest;(2)from 2000 to 2015, water yield and soil conservation showed a downward trend with a decrease of 95.27 mm and 1 081.38 t/hm2, while an increasing trend of carbon storage was found with an increases of 25.77 g C/m2;(3)the area of the first and second type hot spot decreased, while the area of the third type hot spot and non-hot spot increased; forest provided stronger ecosystem services than those of grassland in the study area;(4)from 2000 to 2015, in terms of space, the synergy between the three ecosystem services was getting stronger, which was reflected by the increase of correlation coefficients; according to timelines, the mutual relationships among the three ecosystem services were weakening, showing a decrease in correlation coefficients.The spatiotemporal variation trends of the three ecosystem services in the study area were different. There were the significant synergies among services, and there was also strong and weak change with spatiotemporal variation.
