This　article　selects　138　pairs　of　villages　included　in　the　＂Fujian　Taiwan　Same　Name　Village＂　of　the　Fujian　Taiwan　Border　Museum　in　China　as　the　research　objects.　Using　technologies　and　methods　such　as　geographic　information　system　spatial　analysis,　spatial　composition　analysis,　comparative　research,　and　literature　evidence,　this　study　aims　to　sort　out　the　background　of　the　formation　of　villages　with　the　same　name　in　Fujian　and　Taiwan,　and　analyze　their　spatial　layout　characteristics;　analyze　the　correlation　between　the　layout　of　residential　spaces　in　Fujian　and　Taiwan　villages　with　the　same　name　under　the　influence　of　blood　relationships　from　three　aspects:　overall　settlement　space,　housing　cluster　space,　and　architectural　space.　Results　show　that:　(1)　In　terms　of　site　selection　and　residence,　the　village　with　the　same　name　in　Fujian　and　Taiwan　belongs　to　a　cohesive　type　and　presents　two　clusters,　located　at　the　border　of　Changhua　county　and　Nantou　county　in　Taiwan　province　and　Quanzhou　city　in　Fujian　province.　The　Fujian　Taiwan　villages　with　the　same　name　in　Taiwan　exhibit　similar　geographical　characteristics　to　their　ancestral　land　in　distribution;　(2)　In　terms　of　the　spatial　pattern　of　settlements,　single　surname　villages　with　the　same　name　in　Fujian　and　Taiwan　exhibit　a　spatial　pattern　that　extends　from　the　center　outward,　with　clear　hierarchy　and　complete　structure.　Multi-　surname　villages　with　the　same　name　in　Fujian　and　Taiwan　exhibit　multiple　clustered　clusters　in　terms　of　family　spatial　layout.　The　patriarchal　system　and　ritual　system　occupy　an　important　core　position　in　the　spiritual　consciousness　of　the　Fujian　and　Taiwan　ethnic　groups,　which　is　commonly　manifested　as　the　characteristic　of　cohabitation　based　on　blood　relations;　(3)　In　terms　of　spatial　cluster　layout,　the　villages　with　the　same　name　in　Fujian　and　Taiwan,　under　the　constraints　of　the　patriarchal　system,　jointly　demonstrate　a　consistent　local　ethical　order;　(4)　In　terms　of　architectural　spatial　layout,　the　architectural　structure　layout　presents　clear　priorities,　symmetry　and　regularity,　and　the　spatial　order　layout　presents　characteristics　of　clear　hierarchy　and　hierarchical　division.　By　studying　the　migration　distribution　of　villages　with　the　same　name　in　Fujian　and　Taiwan,　as　well　as　the　correlation　between　spatial　layouts　at　different　scales,　we　found　the　deep　identification　and　attachment　of　the　people　of　Taiwan　province　to　their　ancestral　land　in　the　spatial　evolution　of　historical　changes　and　social　development.　This　is　of　great　significance　for　strengthening　the　same　origin　and　cultural　identity　of　compatriots　on　both　sides　of　the　Taiwan　Straits.　©　2024　Science　Press.　All　rights　reserved.
