Due　to　the　great　application　potential　of　fractional　q-difference　system　in　physics,　mechanics　and　aerodynamics,　it　is　very　necessary　to　study　fractional　q-difference　system.　The　main　purpose　of　this　paper　is　to　investigate　the　solvability　of　nonlinear　fractional　q-integro-difference　system　with　the　nonlocal　boundary　conditions　involving　diverse　fractional　q-derivatives　and　Riemann-Stieltjes　q-integrals.　We　acquire　the　existence　results　of　solutions　for　the　systems　by　applying　Schauder　fixed　point　theorem,　Krasnoselskii＇s　fixed　point　theorem,　Schaefer＇s　fixed　point　theorem　and　nonlinear　alternative　for　single-valued　maps,　and　a　uniqueness　result　is　obtained　through　the　Banach　contraction　mapping　principle.　Finally,　we　give　some　examples　to　illustrate　the　main　results.
