Abstract: MLS-based meshless method is a new numerical method in near few years and has such advantages as only requirement of node information of nodes rather than element over finite element method.Meshless method is applied to construct the field functions including the selection of base function and weight function and the shape function and to compute the derivatives of these both functions. On the basis of hydrogeological conditions in Shoushan region,Anshan City,Liaoning Province, a mathmatical model to solve the two-dimensional plane groundwater flow system with double-layer structure has been set up and the meshless equation to solve the mathematical model bas also been educed.The mathmatics model has been solved using meshless method based on the caliberated parameter.The forecasted groundwater level in the region with this method is consistent with the observed change.

Key words: meshless method, weight function, water level forecast, Shoushan region in Anshan City
