The　functional　division　of　parking　lot＇s　surrounding　areas　is　the　basis　and　the　key　to　study　on　parking　behavior.　In　this　paper,　firstly,　according　to　functional　characteristics,　the　area　surrounding　parking　lot　is　quantified　by　5　indexes　including　location　potential,　bus　accessibility,　public　service　level,　average　housing　price　and　number　of　parking　lots,　which　are　selected　from　4　aspects　including　location,　public　transport,　economic　level　and　transport　facilities　supply;　secondly,　according　to　development　intensity,　the　surrounding　area　is　divided　into　5　categories　through　SPSS　cluster　analysis　method　and　then　the　quantitative　model　of　regional　functional　characteristics　is　worked　out　through　linear　regression　analysis;　finally,　with　the　parking　behaviors　under　different　types　of　regional　functional　characteristics,　it　proves　that　the　regional　functional　characteristics　have　an　obvious　influence　on　parking　behavior.
