In this paper, we mainly use the dynamical systems method to solve the (2 + 1) dimensional KP equation. By introducing the traveling wave transformation, the original (2 + 1) dimensional KP equation is transformed into ordinary differential equations. After that, we analyze the singular points, the corresponding bifurcation and phase diagram of the system. Finally, the solution of the original equation is obtained by using the Maple software, including the sharp wave solutions and periodic wave solutions.
