利用拓展的Riccati方程映射法与变量分离法，得到了(2+1)维广义Nizhnik-Novikov-Veselov(GNNV)系统新的含有两个任意函数的相当广义的变量分离严格解.根据其中的周期波解，找到了该系统的复合波，即在周期波背景下的孤立波，并简要讨论了其演化行为.

Starting from an extended mapping approach and a linear variable separation method, new families of exact solutions with arbitrary functions for (2+1)-dimensional Generalized Nozhnik-Nivikov-Veselov system(GNNV) are derived. We found that some new and interesting complex wave excitations are derived from a periodic wave solution.
