Some simple special Bcklund transformation theoremsare proposed and used to get explicit solutions of the BQGPV equation. Futhermore, all solutions of a secondorder linear ordinary differential equation including an arbitrary function can be used to construct explicit solutions ofthe (2+1)-dimensional BQGPV equation.
