In order to improve the efficiency of regional ecological protection and provide policy basis for scientific decision-making on regional ecological governance, we used the coastal area of Shandong Province as the research area, used the InVEST model and the CASA model to measure the temporal and spatial evolution of water production services, soil conservation, vegetation carbon sequestration, and biodiversity, and used the difference comparison method to explore the temporal and spatial differentiation mechanism of ecosystem service synergy trade-offs, and further used multi-scale geographic weighted regression(MGWR)to analyze the influence of natural factors and human activity factors on synergy trade-offs. The results showed that:(1)in 2018, the average values of water production services and biodiversity in the study area were 605.27 mm/a and 0.28, and the total increasing rates from 2010 to 2018 were 0.21 mm/a and 0.23, respectively; soil conservation and vegetation carbon sequestration were 0.000 73 t/(hm2·a)and 537.56 gC/(m2 ·a), and the total deceleration rates from 2010 to 2018 were 0.62 t/(hm2·a)and 2.1 gC/(m2 ·a), respectively;(2)during the study period, the synergy of ecosystem services had significant spatial heterogeneity; water production services and soil conservation and biodiversity showed strong trade-offs and weak synergy; vegetation carbon sequestration was associated with water production services and soil conservation; biodiversity showed strong synergy and weak trade-offs;(3)there was a correlation among water production services, soil conservation, and vegetation carbon sequestration, which was more affected by natural factors such as slope, elevation, and sunshine hours than human activities, of which positive and negative characteristics and intensity were spatially heterogeneous; the interpretation of the other factors was relatively small and not fixed, and each factor was dynamic and comprehensively affected the changes in the synergy trade-off. In conclusion, the synergy and trade-off of the four ecosystem services in the study area had significant spatial heterogeneity, and the positive and negative factors and intensity of the influencing factors were also spatially heterogeneous, and the results can provide a reference for ecological governance in coastal areas of Shandong Province.
