The full permutation polygon graphic method wasaplied toanalyze thechanging trendsof green space ecological service functions in Huainan CityTheEco-Economic Harmony（EEH） index was used toassssthecoordination betweenecological ser vice valueand socio-economic development intheregion.Results]Theresults indicated that：（1）The total valueof ecosystem services provided by the green space system continued to increase，rising from 2，278.13 x 105 yuan in 2012 to 4，724.59× 105 yuan in 2O22，with a net increase of 245 million yuan and an average annual growth rate of about 7.8% .（2）The order of averagevalue over the yearswasas follows：biodiversity protection > oxygen release>carbonsequestration > cooling>water conservation > dust retention > leisure and recreation > nitrogen oxide absorption.（3） Over the past 1l years，the comprehensiveindicesoftheactualecologicalservicevalueofHuainan's greenspace systemwasO.049，0.116，0.142，0.209，0.266， 0.403，0.428，O.457，O.531，0.706，0.949，respectively，reflectingayear-by-yearimprovementinsustainabledevelopment capacity.（4）TheEEH index forHuainanCityover thepast tenyears wasO.92，indicatinga moderatelevelofeco-economic coordinated development，approachingahigh levelofcoordination.[Conclusion]Theecosystem servicevalue inHuainan City hasbeeincreasingannuall.However，thegrowthrateoftheurbaneconomystillexcededthatoftheecologicalservicesvalue.Futureurbaneconomicdevelopmentshould proritizeecologicalenvironmentprotection，anditisparticularlyimportantto enhance relevant laws and regulations to prevent damage to urban green spaces.
