摘　　要：根据对塔里木盆地露头剖面的层序地层学研究，建立了震旦—泥盆纪古海平面变化曲线。详细分析了氧同位素记录与海平面变化之间的关系，得出了：氧同位素值的增大、减小反映着古海平面的下降、上升的变化的结论。用氧同位素分析结果验证了根据层序地层分析所建立的海平面变化曲线的正确性。并利用氧同位素分析结果定量计算了古海平面的变化幅度。最后阐述了古海平面变化的形成机理。Based on sequence stratigraphy work for the outcrops in Tarim Basin,The author sets up the Sealevel changes curve of sinian period to Devonian period.Then the author studies the relationship between oxygen isotope and sealevel changes and finds the oxygen isotope ratio′s increase and decredse indicating the sealevel′s down and up.The correctness of sealevel changes curve is tested and verified by the result of oygen isotope.The ranges of sealevel changes are calculated.Finally the author elaborates the formation mechanism of sealevel changes of Sinian period to Devonian period in Tarim Basin.
