%X Gravity field of the Earth is a physical property contributed by the gravity to state the space in,on and above the Earth.It exists variation not only on temporal scale but also on spatial scale.The Earth's gravity field observed from space is a consequence of the mass distribution within the Earth system.The Transport of mass within the Earth system will be reflected in the gravity field variation.The temporal variation of it has secular change,seasonal variation,irregular variation,and other scales variation.We mainly review the progress in researches on the temporally varying gravity field.The main reasons contributed to the gravity variation are classified and described respectively in the paper.
