Abstract The determination of space datum and time datum for the computation of the dynamic change of gravity field is discussed.78 issues of observations of gravity network in the Capital area are computed．The dynamic patterns of gravity field in the seismogenic process of several ML＞5.0 earthquakes in North China and the judgement index for the gravity anomaly of gravimetric network in the Capital area are giver．
Key words ：
