A series of Earth's lithospheric magnetic field models,

MF1~MF6, produced by Dr. Stefan Maus and his colleagues according to

data from CHAMP, are recommended in this paper. The author made a

visual comparison between the magnetic anomaly map compiled on the

basis of MAGSAT data and that compiled on the basis of CHAMP data (MF6)

collected over China's continent. It is shown that the anomaly that

appears in the map from MAGSAT（e.g., the anomaly in Tarim Basin）

resolves into several smaller anomalies in the map from CHAMP

(MF3,MF4,MF5,MF6) . Therefore, MF3,MF4,MF5,MF6 are more suitable for

mapping smaller geological features.
