摘　　要：用常规方法计算地震数据分形关联维数需要花费很长的计算时间。作者在本文中提出了一种基于梯形法和常规的最小二乘拟合相结合的分形关联维数计算方法 ,将本文算法应用于实际地震资料处理 ,可以快速确定地震道时间序列的无标度区分与分维数。Computing fractal associated dimension parameters of seismic data usually costs much time with the conventional computing method. An improved method based on combination the trapezoid method with the conventional least square fitting method was presented in this paper. Applied to practical seismic data processing, the method can compute the fractal associated dimension very fast.
