Abstract：In the area where there is no field source, gravity field and magnetic field have similar properties. They all satisfy Laplace equation. In the area in which we need solution, the boundary low gradient values can be considered as the values of regional background field, so that separating out gravity anomalous field or magnetic anomalous field becomes the problem of how we compute the boundary value of Laplace equation. The boundary value problem can be solved by using boundary element method, which is convenient and accurate.
