利用改进的Riccati方程映射法，得到了变系数(2+1)维 Broer-Kaup 系统的孤波解、周期波解和变量分离解.根据得到的孤波解，构造出了系统的几种不同形状的孤子结构，研究了孤子的裂变和湮没现象.

By an improved mapping approach, a series of excitations of the (2+1)-dimensional Broer-Kaup system with variable coefficients is derived. Based on the derived solitary wave excitation, we obtain some special soliton structures and study the phenomena of fission and annihilation of solitons.-
