This　paper　focuses　on　the　analysis　of　the　flow　field　of　Danjiangkou　Reservoir　under　the　action　of　wind　stress.　Based　on　the　analysis　of　the　annual　wind　field　data　of　Danjiangkou　Reservoir,　the　three-dimensional　hydrodynamic　model　of　Danjiangkou　Reservoir　was　established.　The　distribution　of　water　flow　field　in　the　reservoir　area　under　five　different　wind　directions　and　two　different　wind　speeds　was　studied.　The　simulation　results　were　compared　with　the　flow　field　without　wind.　The　results　show　that　when　the　wind　speed　in　the　reservoir　area　is　3.3m/s,　the　surface　velocity　and　flow　direction　change　less　under　the　same　wind　conditions　as　the　potential　flow　direction.　Under　the　wind　condition　opposite　to　the　potential　flow　direction,　the　reservoir　area　is　locally　generated.　The　small　circulation　and　surface　flow　are　more　disordered;　when　the　wind　speed　reaches　10.0m/s,　under　the　same　wind　condition　as　the　potential　flow　direction,　the　surface　velocity　of　the　reservoir　area　increases　significantly.　Under　the　wind　condition　opposite　to　the　direction　of　the　potential　flow,　a　stable　counterclockwise　circulation　is　generated,　and　the　wind　direction　dominates　the　surface　layer.　seriously　affecting　the　flow　field　distribution　in　the　reservoir　area.　The　research　results　in　this　paper　can　provide　support　for　the　reservoir　in　the　formulation　of　emergency　water　pollution　emergency　strategy　and　the　formulation　of　real-time　scheduling　plan.　©　The　Authors,　published　by　EDP　Sciences,　2018.
