%X The semi-inverse method is proposed by He to establish the generalized variational principles for physical problems,which can eliminate variational crisis brought by the Lagrange multiplier method.Via the He' s semi-inverse method,a family of variational principles is constructed for the Boussinesq equation systems and variant Boussinesq equation systems of fluid dynamics.The obtained variational principles have also proved to be correct.
