摘　　要：通过地球磁场的研究,认为如果研究的对象是区域地质情况,这时使用的正常场就应是地球的基本场。如果我们研究的对象是局部磁性地质体引起的磁场,若区域场较小,正常场可确定为是基本场;若区域场较强,应根据测区内磁场的分布情况,实测确定。through the study of the earth＇s magnetic field,as if the object of research is the regional geological conditions,the use of normal field should be the basic field of earth.If the object of our study is the local magnetic geologic body caused by the magnetic field,that if regional magnetic anomaly field is small,the normal field can be determined as the basic field;if the field is strong,the normal field is determined according to the distribution of the magnetic field measured within the area.

关 键 词：正常场 地球基本磁场 磁异常场 区域磁异常场
