摘　　要：应用WTC截断法获得了(2+1)维高阶Broer Kaup方程的一个含有三个任意变量函数的一般解析解.从一般解出发,选取适当的任意函数可以分别构造出多种特殊的局域相干结构,如多dromion解、双孤子解、环孤子解等,并通过解析和图示方法揭示了其奇异性质.With the Weiss-Tabor Carnevale truncation method, the （2＋1） dimensional higher order Broer Kaup equation is solved, and it obtained a general analytical solution including three arbitrary functions. Staring from the general solution, some special types of localized coherent structures such as multi-dromion solutions, two soliton solutions and ring soliton solution are built by selecting proper arbitrary functions respectively. The interesting novel features and evolution properties are revealed analytically and graphically.
