摘　　要：针对在解析古剩磁偏角变化时遇到的传统赤平投影方法已不适用的问题,采用改进的赤平投影方法并将其应用于古剩磁偏角变化的解析中。结果认为:改进的赤平投影方法不仅能够确定研究点在地球表面上的地理坐标,还能够解析研究点运动轨迹上任意一点处的古剩磁偏角,指导岩石圈板块运动引起古剩磁偏角变化规律的研究。In view the problem of the traditional of stereo graphic projection method used in the analysis of ancient magnetic declination geologic,it is necessary to improve the stereographic projection method.If the stereographic projection method is modified and applied in the analysis of the changes of ancient magnetic declination,we can conclude that the improved stereographic projection can be used not only to determine the geographical coordinates of the survey points on the Earth but also to interpret the ancient magnetic declination angle at every moving point,The method of stereographic projection can also be used to research the change regulations of ancient remain magnetic declination generated by the lithosphere plate motions.
