Objectives: The game between socio-economic development and ecological has always been the core issue in coal areas, but internal mechanism of tradeoff cooperative dynamic change ecosystem services mining areas under long-term mineral resources is still lacking in-depth research. Methods: Therefore, taking Shendong area as an example, this study used InVEST model to evaluate changes four major service functions from 1990 2020, namely, water yield (WY), net primary productivity (NPP), soil conservation (SC) habitat quality (HQ). Meanwhile, correlation analysis was explore trade-off synergistic relationship among these services. On basis, coupling effect further discussed by using constraint line method. Finally, key drivers trade-offs/synergies region are explored geodetectors explanations each influence factor for RMS errors obtained. Results: results show that 1) retention decrease first then increase, increase slowly, mainly southeast area. 2) In terms relationship, all showed hump-like is, there obvious threshold effect. 3) area, dominant services, occurs quality. 4) driving tradeoff/synergy, land use type, temperature, rainfall main factors cause spatial differentiation synergy intensity Conclusions: provide a scientific basis improvement environment sustainable utilization exploitation.
