AB - This paper mainly investigates the reductions of an integrable coupling of  the Levi hierarchy and an expanding model of the (2+1)-dimensional  Davey-Stewartson hierarchy. It is shown that the integrable coupling system  of the Levi hierarchy possesses a quasi-Hamiltonian structure under certain  constraints. Based on the Lie algebras construct, The type abstraction  hierarchy scheme is used to gener­ate the (2+1)-dimensional expanding  integrable model of the Davey-Stewartson hierarchy.
