The　Min　Delta　urban　agglomeration　includes　three　cities　(Xiamen,　Quanzhou,　and　Zhangzhou)　and　is　an　open　coastal　area　in　China.　Since　the　21st　century,　rapid　urbanization　has　seriously　affected　the　ecological　security　and　ecosystem　services　function　of　the　region　and　has　restricted　the　sustainable　development　of　the　local　economy　and　society.　For　this　reason,　understanding　the　trade-offs　and　synergies　of　ecosystem　services　in　the　Min　Delta　urban　agglomeration　is　of　considerable　significance　to　the　coordinated　linkage　management　of　ecological　security　and　the　sustainable　development　of　social　economy　in　this　region.　This　paper　estimated　four　kinds　of　ecosystem　services　(water　conservancy,　soil　conservation,　NPP(Net　primary　productivity),　and　food　supply)　in　the　Min　Delta　urban　agglomeration,　and　the　spatial-temporal　dynamics　and　trade-offs-synergies　among　the　ecosystem　services　were　analysed　using　correlation　and　spatial　analyses.　Moreover,　the　spatial　distribution　and　trade-offs　of　ecosystem　services　in　2030　were　simulated　under　different　scenarios.The　results　showed　that:　From　2005　to　2015,　trend　for　all　four　types　of　ecosystem　services　were　decreased,　and　there　was　a　synergies　relationship　between　water　conservancy,　NPP　and　soil　conservation　services.　However,　there　was　a　trade-offs　between　food　supply　service　and　the　other　three　services.　From　2005　to　2015,　the　trade-offs　and　synergies　between　the　four　services　remained　unchanged,　the　degree　of　complex　changes　have　taken　place.　In　terms　of　spatial　distribution　characteristics,　the　degree　of　ecosystem　service　trade-offs　and　synergies　in　Jinjiang　river　basin　is　higher　than　that　in　Jiulong　river　basin.　The　trade-offs　and　synergies　relationship　of　ecosystem　service　in　three　cities　of　Min　Delta　urban　agglomeration　presents　uniformly　in　Xiamen　＞　Quanzhou　＞　Zhangzhou.　In　different　scenario　Settings,　there　was　a　significant　decrease　in　the　four　ecosystem　services　under　the　natural　scenario,　and　the　synergistic　relationship　was　mainly　in　a　downward　trend,　while　the　trade-offs　relationship　was　intensified.　Compared　with　the　planning　scenario,　the　synergistic　relationship　under　the　protection　scenario　was　higher　and　the　trade-offs　relationship　was　lower.　©　2019　Science　Press.　All　rights　reserved.
