At　present,　most　of　the　existing　studies　on　traditional　residence　are　focused　on　conservation　and　reuse,　discussion　on　their　environmental　adaptability,　and　the　design　wisdom　of　traditional　villages　in　terms　of　disaster　prevention　and　mitigation　and　environmental　adaptability　has　not　been　fully　explored.　Traditional　villages　along　the　coast　of　Fujian　are　divided　into　two　categories:　one　is　the　traditional　villages　that　were　coastal　defence　guards　in　the　Ming　dynasty　and　Qing　dynasty;　the　other　is　the　traditional　villages　that　have　been　transformed　defence　functions.　The　new　villages　designed　after　the　1980s　are　different　in　terms　of　street　layout　and　architectural　forms,　with　stronger　wind　in　the　village.　A　comparative　study　of　old　and　new　villages　can　help　us　understand　the　wisdom　of　traditional　villages　and　preserve　and　utilize　them　better.　This　paper　thus　takes　Qinjiang　Village　in　Fuzhou　City,　Fujian　Province　as　a　case　to　quantitatively　summarizes　the　relationship　between　street　layout　and　spatial　morphological　characteristics　of　historical　villages　and　their　adaptability　to　wind　environment,　by　comparing　the　spatial　integration　of　the　village　and　its　adaptation　to　the　sea　wind　environment　are　analysed　by　CFD　software　simulation　with　Depthmap　of　Space　Syntax.　concludes　that　crossroads　have　better　wind　protection　than　T　junctions　for　street　layout　under　the　same　wind　effect;　the　street　height　to　width　ratio　is　inversely　proportional　to　the　average　wind　speed;　the　activity　plazas　properly　interspersed　between　streets　are　conducive　to　optimising　the　wind　environment.　　©　2024　Author(s).
