Landslides　frequently　occur　in　heavily　vegetated　areas　of　southeast　Fujian　Province　due　to　typhoon　rainstorms.　Investigating　the　failure　mechanisms　and　evolution　patterns　of　landslides　influenced　by　vegetation,　rainfall,　and　strong　winds　is　crucial　for　disaster　mechanism,　monitoring,　and　early　warning　of　typhoon-induced　landslides　in　densely　vegetated　regions.　This　study　focuses　on　the　Yangxie　landslide　in　Yongtai　County,　Fujian　Province,　investigating　response　patterns　and　analysis　methods　for　vegetated　slope　stability　under　wind-driven　rain　conditions.　Pulling　tests　on　moso　bamboo　and　single-ring　infiltration　tests　were　conducted,　integrating　the　Green-Ampt　model　and　infinite　side　slope　model.　Detailed　main　results　include:　1)　Bamboo’s　maximum　wind　resistance　ranges　from　18　m/s　to　30　m/s,　corresponding　to　wind　forces　of　8　to　11.　2)　Soil　infiltration　capacity　in　the　windward　area　increases　with　wind　speed,　remaining　constant　at　0–12　m/s　but　rising　rapidly　beyond　12　m/s.　3)　The　wetting　front’s　migration　speed　in　the　root-soil　zone　accelerates　with　increasing　wind　speed　and　rainfall.　Typhoons　disturb　soil　by　swaying　vegetation　to　create　preferential　flow,　mainly　accelerating　the　wetting　front’s　migration　speed.　Wind　speed　significantly　impacts　soil　infiltration　capacity　under　wind,　rain,　and　vegetation　interactions.　4)　During　typhoon　rainstorms,　wind　loads　enhance　rainfall　infiltration　in　the　root-soil　zone　through　vegetation,　thereby　speeding　up　the　wetting　front’s　migration.　This　process　is　critical　for　typhoon-induced　landslide　occurrence　and　development.　©　2024　Biodiversity　Research　Center　Academia　Sinica.　All　rights　reserved.
