摘　　要：We explore the multisymplectic Fourier pseudospectral discretizations for the (3+1)-dimensional Klein-Gordon equation in this paper.The corresponding multisymplectic conservation laws are derived.Two kinds of explicitsymplectic integrators in time are also presented.

关 键 词：multisymplectic pseudospectral （3＋1）-dimensional Klein Gordon equation
