The　aim　of　this　paper　is　to　investigate　the　dynamic　behaviors　of　a　harvesting　Lotka-Volterra　commensalism　model　incorporating　partial　closure　for　the　populations.　By　analyzing　the　characteristic　equation　of　the　variational　matrix,　sufficient　conditions　which　ensure　the　local　stability　of　the　equilibria　are　obtained;　By　applying　the　differential　inequality　theory　and　the　Dulac　criterion,　sufficient　conditions　which　ensure　the　globally　asymptotical　stability　of　the　equilibria　are　obtained;　Our　study　shows　that　depending　on　the　fraction　of　the　stock　available　for　harvesting,　the　system　maybe　extinction,　partial　survival　or　two　species　coexist　in　a　stable　state.　The　dynamic　behaviors　of　the　system　becomes　complicated　compared　with　the　non-harvesting　system.　Numeric　simulations　are　carried　out　to　show　the　feasibility　of　the　main　results.　©　2018　Deng　and　Huang.
