摘  要:By the Backlund transformation method, an important (2+1)-dimensional nonlinear barotropie and quasigeostrophic potential vorticity (BQGPV) equation is investigated. Some simple special Backlund transformation theorems are proposed and used to get explicit solutions of the BQGPV equation. Furthermore, all solutions of a second order linear ordinary differential equation including an arbitrary function can be used to construct explicit solutions of the (2+1)-dimensional BQGPV equation. Some figures are also given out to describe these solutions.
