To　promote　the　healthy　and　sustainable　development　of　territorial　space,　it　is　necessary　to　identify　study　the　coordinate　relationship　between　the　production-living-ecology　functions　(PLEFs)　of　land　at　the　township　level.　This　study　took　the　towns　in　the　Beijing　Plain　area　as　a　case　to　establish　an　evaluation　system　of　PLEFs,　and　used　the　coupling　coordination　degree　model　to　reveal　the　spatiotemporal　evolution　characteristics　of　the　functions＇　relationship.　Results　show　that　the　PLEFs　in　the　township　areas　of　Beijing　Plain　have　obvious　temporal　and　spatial　differences.　The　production　function　and　living　function　increase　though　they　fluctuated.　The　ecological　function　decreases　first　and　then　increases.　For　the　spatial　distribution,　the　production　function　is　higher　in　the　south　than　in　the　north,　and　the　ecological　function　presents　a　declining　trend　from　north　to　south.　The　living　function　decreases　outwards　with　the　towns　around　the　central　urban　area　as　a　core.　The　coupling　coordination　degree　(CCD)　increases　except　for　that　of　the　production-ecology　first　decreases　and　then　increases.　Most　of　the　towns　are　coordinated,　while　the　uncoordinated　villages　and　towns　are　mainly　located　on　the　north-south　and　east-west　axes　around　the　central　urban　area.　Towns　with　different　CCDs　are　affected　differentially　by　functions,　therefore　targeted　promotion　strategies　should　be　adopted　for　towns　with　different　levels　of　coupling　coordination　in　the　future.　©　2023　Beijing　University　of　Technology.　All　rights　reserved.
