Urban　parks　play　a　distinctive　and　important　role　in　satisfying　residents＇　demands　on　leisure　and　recreation,　and　thus　have　become　the　focus　of　research　in　the　field　of　urban　planning　and　sustainable　development.　This　paper　used　equity　as　indicator　to　combine　both　the　supply　and　demand　sides　of　urban　park　service.　Taking　Xiamen　as　the　study　case,　the　relationship　between　spatial　distribution　of　population　and　park　services　was　analyzed.　The　results　show　that　while　population　density　has　a　significant　spatial　relationship　with　urban　park　service　level　at　the　city　scale,　Xiamen　has　the　problem　of　neglecting　the　equity　of　urban　park　service　between　people　and　regions　within　the　city.　The　proposed　approach　builds　up　the　linkage　between　urban　park　service　and　urban　population　in　order　to　evaluate　the　performance　of　urban　park.　Although　the　mechanism　remains　to　be　discussed,　this　study　provides　a　useful　auxiliary　tool　for　constructing　a　guideline　for　urban　green　space　planning,　since　urban　park　is　increasingly　seen　as　a　kind　of　restricted　public　resource　and　ensuring　its　equity　should　be　an　important　task　for　city　mangers.
