Abstract：The current seismic numeric modeling algorithm can9 t adaptively adjust the size of special network,so a great amount of storage space and computation time are needed for computing the wavefield and the precision of local simulated wavefield is not higher at the same time.The paper presented an adaptive network algorithm on the basis of average interpolation wavelet and gave the wavelet adaptive numeric algorithm of 2-D one-order pressure — velocity scalar equation in non-ho-mogeneous medium.The method operates the issue of seismic wave propagation in the general boundary condition in the interpolation space of wavelet and the non-uniform change of wavefield responses adaptively,which has greatly improved the simulated precision and computational efficiency.The results of numeric modeling showed that the method is correctness and effectiveness.
