Understanding　the　complex　relationships　of　tradeoffs　and　synergies　among　ecosystem　services　(ESs)　is　essential　to　achieve　a　comprehensive,　coordinated,　and　sustainable　development　for　human　well-being.　However,　the　quantitative　measurement　for　the　properties　and　intensities　within　these　relationships　as　well　as　the　deeper　exploration　of　its　for-mation　mechanism　from　a　spatial-explicit　perspective　is　still　a　challenge.　In　this　study,　a　comprehensive　and　general　methodology　was　developed　to　quantitatively　illustrate　the　intensities　of　tradeoffs/synergies　among　pairwise　ESs　and　explore　the　spatially　heterogeneous　relationships　between　these　relations　and　several　socio-ecological　drivers,　in-tegrating　InVEST,　geographical　detector　and　multi-scale　geographically　weighted　regression　(MGWR)　methods.　The　results　indicated　that　(1)　the　properties　and　intensities　of　tradeoffs/synergies　among　various　ESs　varied　greatly　over　space　and　presented　significant　clustered　distribution　patterns;　(2)　different　relations　between　ESs　were　dominated　by　diverse　drivers　and　the　combined　effects　from　multiple　factors　were　stronger　than　any　single　one　within　this　pro-cess.　The　tradeoffs/synergies　between　soil　conservation　and　other　ESs　were　mainly　affected　by　geomorphological　drivers　including　elevation　and　slope,　while　relations　involved　habitat　quality　could　be　attributed　to　vegetation　and　climate　drivers　such　as　precipitation　and　vegetation　fractional　cover.　The　relationships　among　ESs　were　more　suscep-tible　to　topographic　and　anthropogenic　drivers　when　concerning　the　carbon　storage　service;　(3)　compared　to　global　ordinary　least　squares　and　local　geographically　weighted　regression　(GWR),　the　MGWR　obtained　better　performance　in　explaining　relationships　between　tradeoffs/synergies　among　ESs　and　potential　drivers　by　operating　different　spatial　scales.　Accordingly,　several　spatially　targeted　ecological　measures　were　proposed　and　recommended　to　reduce　ESs　tradeoffs　and　ultimately　achieve　better　synergies.　This　research　could　enrich　the　methods　in　revealing　the　complex　evolvement　mechanism　behind　the　tradeoffs/synergies　among　ESs　and　the　proposed　framework　also　provided　a　new　perspective　in　the　field　of　ESs　tradeoffs/synergies　studies　and　might　be　valuable　guidance　for　other　regions　worldwide.
