Abstract: With the help of the symbolic computation system Mathematica,the new exact solutions of the(2+1)-dimensional dispersive long wave equation are derived in terms of both extended F/G-expansion method and variable separation method.By choosing the appropriate function,the bright and dark dromion solution and the periodic solitary wave solution of the(2+1)-dimensional dissipative long wave equation are obtained.
