In this paper, we first obtain the existence of positive ground state solutions for the following critical fractional Laplacian system:( − Δ ) s u = μ 1 | u |2 s ∗ − 2 u + α γ2 s ∗| u | α − 2 u | v | βinℝ n ,( − Δ ) s v = μ 2 | v |2 s ∗ − 2 v + β γ2 s ∗| u | α | v | β − 2 vinℝ n ,then we give a complete classification of positive ground state solutions with different Morse index. More precisely, we show that if ( u ,  v ) be any positive ground state solution of system (1.1), then ( u ,  v ) must be ( C 1 U ϵ ,  y ,  C 2 U ϵ ,  y ) type with Morse index 1 and Morse index 2, where U ϵ ,  y is a positive ground state solution for a given equation.
