Correlation between the crystal lattice and the vortex lattice in anisotropic (uniaxial) type-II superconductors due to magnetoelastic interactions is studied theoretically. Within the strain-dependent Ginzburg-Landau model, the energy of the magnetoelastic interaction of the vortex lattice is evaluated with the {Delta}{ital V} effect (difference of specific volumes of normal and superconducting phase) as the main source of the elastic strain. For NbSe{sub 2} in tilted fields near the upper critical field {ital H}{sub {ital c}2}, the vortex lattice is the same as obtained within the London model in fields well below {ital H}{sub {ital c}2} with magnetoelastic interactions taken into account.
