摘　　要：综述了地球重力场研究对揭示其运动和时变与地震之间的关系的重要性 ;介绍了当今国际固体地球科学与防灾研究的一个新热点———卫星重力学与重力卫星研究的进展。随着重力卫星计划的实施 ,地球重力场的研究也将因此产生质的变化。文章对CHAMP、GRACE和GOCE重力卫星作了介绍。The importance of research on the gravity field of the earth for revealing the relationship between its movement as well as temperal variation and earthquake is summarized. A new hot point of research on solid earth science and disaster preparedness at present in the world -- progress in research on satellite gravimetry and gravity satellite is introduced. Along with the implementation of gravity satellite plans, therefore, research on the gravity field of the earth will change in quality.Finally, the paper introduces the gravity satellites of CHAMP,GRACE and GOCE.
