It is the premise of ecosystem management to clarify the characteristics and driving mechanism of the comprehensive relationship between various ecosystem services. In this paper, we used meteorological, land use, NDVI, soil and other data to quantitatively calculate and analyze water production, NPP and soil conservation services and their trade-offs and synergies in Shiyang River Basin from 2003 to 2018 based on InVEST model, CASA model and RUSLE model, with the help of correlation analysis method. Moreover, we proposed a method to identify the comprehensive relationship ecosystem services(CRES). Study on the spatial differentiation characteristics of the CRES in Shiyang River Basin, and the driving mechanism was revealed based on the geographic detector method. The results are shown as follows.(1)From 2003 to 2018, ecosystem water production and soil conservation services in Shiyang River Basin showed a downward trend and NPP showed an upward trend. Ecosystem water production services and soil conservation services in Shiyang River Basin were mainly collaborative, and water production services and NPP, NPP and soil conservation services were mainly balanced.(2)The comprehensive relationship of ecosystem services in Shiyang River Basin had obvious spatial heterogeneity. The regions with comprehensive relationship dominated by full synergy mainly distributed in Su'nan County, and the regions with comprehensive relationship dominated by full trade-off mainly distributed in Qilian Town of Tianzhu County and Xiqu Town, Donghu Town and Shoucheng area of Minqin County. The regions with comprehensive relationship dominated by trade-off account for the largest proportion of Shiyang River Basin, with the value of 74.44%.(3)Altitude was the leading factor to determine the spatial differentiation of CRES in Shiyang River Basin, there were differences in the main factors of sub watershed detection, the interaction of two factors was more powerful in explaining the spatial differentiation of CRES. To sum up, most areas of the Shiyang River Basin are still dominated by trade-offs, and it is urgent to coordinate the relationship between ecosystem services through ecosystem management. The ecological problems of Qilian Town in Tianzhu County, Xiqu Town, Donghu Town and Shoucheng area in Minqin County need to be focused and prioritized.
