A lot of numerical simulations indicate that both SVD and LSQRD are very effectively applied to inversion of surface wave dispersion. Using SVD method through resolution matrix,information matrix and covariance matrix,the solutions can be evaluated mathematically, objectively and effectively, while LSQRD is more useful to solve a large sized sparse linear system because if has high efficiency in computation and strong noise abatement and needs small store spaces, so that SVD algorithm should be adopted in inversion of linear system under fast computations and big store spaces of present computers if the quantity of data is not too large.
