This　paper　proposes　a　modified　Leslie-Gower　predator-prey　model　incorporating　saturation　wind　effects　to　explore　the　nonlinear　impact　of　wind　speed　on　ecosystem　dynamics.　By　introducing　a　saturation　function　ϕ(ω)=1+ω,k+ω　we　analyze　the　system’s　stability,　persistence,　and　bifurcation　behavior.　Key　findings　include:　1)　Critical　Wind　Speed　(ωc):　A　critical　wind　speed　ωc　is　identified,　beyond　which　the　system　transitions　from　a　coexistence　state　to　prey　extinction,　highlighting　wind　speed’s　role　in　ecosystem　stability.　2)　Saturation　Effect:　At　low　wind　speeds,　predation　rate　increases　linearly　with　wind　speed　but　saturates　at　high　wind　speeds,　reflecting　organisms’　adaptive　strategies　to　extreme　conditions.　This　saturation　effect　balances　predation　pressure　and　prey　survival.　3)　Global　Stability　and　Persistence:　The　positive　equilibrium　E∗　is　globally　asymptotically　stable　when　r　＞　αϕ(ω)c,　ensuring　predator-prey　coexistence.　The　system　is　also　shown　to　be　persistent　under　this　condition.　4)　Transcritical　Bifurcation:　The　system　undergoes　a　trans-critical　bifurcation　at　ωc,　where　the　positive　equilibrium　E∗　collides　with　the　prey-free　equilibrium　E1(0,　c),　leading　to　a　state　transition.　Numerical　simulations　validate　the　theoretical　results,　demonstrating　how　wind　speed　influences　ecosystem　dynamics.　This　study　provides　a　new　perspective　on　the　interplay　between　climatic　factors　and　biological　interactions,　with　implications　for　ecological　conservation　and　pest　control.　©　2025,　International　Association　of　Engineers.　All　rights　reserved.
