• extended mapping approach
• generalized DLW systems
• nonpropagating soliton

An extended mapping approach is used to obtain a new type of variable separation excitation, with three arbitrary functions, of the 2+1-dimensional generalized dispersive long wave equation (DLWE). By selecting appropriate functions, the richness of nonpropagating solitons, such as nonpropagating dromion, nonpropagating ring, nonpropagating lump, and nonpropagating foldon, etc., is displayed for the (2+1)-dimensional generalized dispersive long wave equation (DLWE) in this paper. Meanwhile, we conclude that the solution nu(1) and nu(2) are essentially equivalent to the "universal" formula.
