In　the　current　manuscript,　a　two-patch　model　with　the　Allee　effect　and　nonlinear　dispersal　is　presented.　We　study　both　the　ordinary　differential　equation　(ODE)　case　and　the　partial　differential　equation　(PDE)　case　here.　In　the　ODE　model,　the　stability　of　the　equilibrium　points　and　the　existence　of　saddle-node　bifurcation　are　discussed.　The　phase　diagram　and　bifurcation　curve　of　our　model　are　also　given　as　a　results　of　numerical　simulation.　Besides,　the　corresponding　linear　dispersal　case　is　also　presented.　We　show　that,　when　the　Allee　effect　is　large,　high　intensity　of　linear　dispersal　is　not　favorable　to　the　persistence　of　the　species.　We　further　show　when　the　Allee　effect　is　large,　nonlinear　diffusion　is　more　beneficial　to　the　survival　of　the　population　than　linear　diffusion.　Moreover,　the　results　of　the　PDE　model　extend　our　findings　from　discrete　patches　to　continuous　patches.　©　2023　American　Institute　of　Mathematical　Sciences.　All　rights　reserved.
