Abstract: Ansatz method and the theory of dynamical systems are used to the study of the traveling wave solutions for the generalized Drinfeld-Sokolov equations.Under two groups of the parametric-conditions,more solitary wave solutions,kink and anti-kink wave solutions and periodic wave solutions were obtained.Exact explicit parametric representations of these travelling wave solutions are given.-
