Dockless　sharing　bicycles　are　one　of　the　most　effective　options　for　connecting　to　the　subway.　However,　the　uneven　spatial-　temporal　distribution　of　sharing　bicycles　has　caused　great　inconvenience　to　users　and　managers,　especially　during　the　morning　peak　period,　which　will　greatly　reduce　the　operating　efficiency　of　a　transportation　system.　Therefore,　studying　the　characteristics　of　spatial-temporal　distribution　of　dockless　sharing　bicycles　used　to　connect　to　the　subway　has　certain　significance　for　improving　the　commuting　efficiency　during　the　morning　peak　period.　In　order　to　understand　the　spatial-temporal　characteristics　of　feeder　metro　riding,　this　paper　takes　Xiamen　city　as　the　experimental　area,　takes　the　riding　of　feeder　metro　stations　during　the　morning　peak　as　the　main　research　object,　proposes　a　new　method　to　establish　the　attraction　area　of　metro　stations　based　on　travel　OD,　and　proposes　a　bicycle　clustering　method　considering　metro　stations　based　on　travel　characteristics.　This　article　also　analyzes　the　overall　travel　balance　of　each　subway　station　during　the　morning　rush　hour　from　the　perspective　of　mathematical　statistics,　tide　ratio　statistics,　and　the　point　of　attraction　area,　and　analyzes　the　spatial-　temporal　balance　of　cycling　around　subway　stations　at　different　times　during　the　morning　rush　hour.　Through　analysis,　the　similarities　and　differences　of　the　balance　of　each　subway　station　under　three　perspectives　are　obtained.　The　results　show　that:　According　to　the　characteristics　of　the　tide　ratio,　the　connection　function　of　the　subway　station　for　cycling　can　be　divided　into　4　categories:　the　start　type,　balanced　type,　arrival　type,　and　not　suitable　for　connecting　to　the　subway　type,　reflecting　the　overall　connection　characteristics　of　each　subway　station;　The　attraction　area　of　the　subway　station　connecting　to　the　riding　is　different　from　the　characteristics　of　the　tide　ratio,　and　its　main　influencing　factors　are　the　geographic　location　of　the　subway　station　and　the　surrounding　land　use　type;　For　the　analysis　results　of　the　spatial-temporal　balance,　the　tide　ratio　has　no　significant　impact　on　the　spatial-temporal　balance　level,　and　the　major　influencing　factor　is　the　surrounding　land　use　type.　The　analysis　results　can　reflect　the　difference　in　the　operation　of　sharing　bicycles　that　connect　to　the　surrounding　subway　stations　during　the　morning　rush　hours　in　Xiamen　and　the　efficiency　of　connecting　to　the　subway,　so　as　to　support　the　scheduling　and　supervision　of　key　areas　of　bicycle　sharing　companies.　©　2022,　Science　Press.　All　right　reserved.
