Abstract：Based on Point of Interest geospatial big data，using spatial analysis methods such as global spatial autocorrelation，average nearestneighborindex，bufferanalysis，kerneldensityanalysis，andwiththehelpofcoupling coordination model，thespatial features ofrecreationalandresidential spacesand the couplingandcoordination relationshipinthemainurbanareaofJinanCityareexplored.Theresultsshowthat：First，recreationalandresidential spaces inthe main urbanareaofJinan have significantpositive spatialcorrelations，presentingapatternofagglomeration distribution.In terms of agglomeration intensity，itis manifestedas“commercial and entertainmentcategory > sports and fitness category > residential space > natural ecologycategory > cultural and leisure category”.Second，the spatial distributionofthetwofunctions issimilar，both showing significant homogeneityin spatial structure，following the differentiation lawof“core-edge”.Third，thetwo functional spacesconform tothe“distance-quantity”function atenuationrelationship.Thenumberofrecreationalspacessignifcantlydecreasesas thedistancefromtheresidentialarea increase，andvarious recreational spacesare mainlyconcentratedwithinaradiusof5OOmeters radius fromtheresidential space.Fourth，the spatial coupling and coordination between recreationand residence functions has strong spatial heterogeneity.Thecouplingsituationofrecreationandresidencespaces intheurbancentralareaisrelativelygood，while thatintheperipheralareasisrelativelypoor.IngeneralcrossJinan’smainurbanarea，intermediatesynergycategories dominatethespatialintegrationspectrum，whilehigh-intensitysynergydistrictsconstitutethesmallstproportioninthe couplingrelationshipmatrix.Therefore，itis suggestedthatthecoordinateddevelopmentofrecreationalandresidential spaces inthe mainurban areaof Jinan be promoted fromaspects such as optimizing the functionsofthecenter and expanding theconfigurationof theperiphery，buildinga15-minute living circle，improvingqualityand eficiency to promote integration，and coordinating urban space and economic development.
