The invention relates to a method for preparing a metal organic framework material in a green mode. The method for preparing the metal organic framework material in the green mode comprises the stepsthat a certain proportion of a transition metal compound, an organic ligand and a solvent are prepared, and a metal organic framework material is rapidly prepared by simple grinding under mild conditions. The method for preparing the metal organic framework material in the green mode is simple in preparation process, and mild in preparation condition, no waste liquid is caused, and the prepared metal organic framework material has uniform particle size, and has potential application prospects in the fields of gas separation and storage, heterogeneous catalysis and drug release.
