摘　　要：利用古地磁数据,结合极射赤平投影方法,开展确定板块运动方法的研究。将其应用到印度板块137Ma至今运动规律的研究中,确定印度板块的运动轨迹为:印度板块于137Ma^65Ma向北微偏西向运动;65Ma^35Ma向北偏西30°方向运动;35Ma至今向北偏东60°方向运动。可将该方法进一步应用到研究其他板块的运动规律中。By using the paleomagnetic data,and combining with stereographic projection method, this paper carries out the research on the determination of plate movement method, and applies it to the research on the Indian plate 137Ma-today movement law which determines the movement locus of the Indian plate： In 137Ma-65Ma, the Indian plate moved to the north west direction; in 65Ma-35Ma, the Indian plate moved to the north west 30~ di- rection; 35Ma-today, the Indian plate moved to the north east 60° direction. And this method can be applied to the research of other plate movement laws.
