A　two　species　commensal　symbiosis　model　with　Holling　type　functional　response　and　density　dependent　birth　rate　takes　the　form　(Formula　presented)　is　proposed　and　studied　in　this　paper.　For　autonomous　case,　i.e.,　aij,　bi,　i　=　1,　2,　j　=　1,　2,　3,　4　p　and　c1　are　all　positive　constants,　p　≥　1,　sufficient　conditions　which　ensure　the　local　and　global　stability　of　the　boundary　equilibrium　and　positive　equilibrium　are　obtained,　respectively;　For　non-autonomous　case,　i.e.,　aij,　bi　and　c1　are　all　continuous　functions　bounded　above　and　below　by　positive　constans,　p　≥　1　is　a　positive　constant,　sufficient　conditions　which　ensure　the　permanence　and　partial　survival　of　the　system　are　obtained,　respectively.　Sufficient　conditions-p　which　ensure　the　existence　of　at　least　one　positive　T-periodic　solution　is　obtained.　Our　study　shows　that　the　birth　rate　of　species　and　the　commensal　intensity　between　the　species　play　important　role　on　the　dynamic　behaviors　of　the　system.　©　2019,　International　Association　of　Engineers.　All　rights　reserved.
