| 摘 要： | 根据青藏高原隆升的数值模型,利用最新地磁极性资料重新计算了高原隆升随时间的变化.在高原的隆升史中,先后有3次达到了H≥Hc(凝结高度),这亦是3个典型的季风气候期.地磁极性强正向期对应着高原的强隆升期,同时也对应着低海平面期;长反向期则伴随着高原的夷平期和高海平面期,但海平面变化比地磁场极性转变平均要晚0.8～1.0MaB.P..

| Abstract: | The time-variation of its uplift was recalculated by using new geomagnetic polarity data on basis of numeric model of the Qinghai-Xizang Plateau rising. In the rising history, the condensation level (H≥H c) was up to 2 000m three times, and at the same time there were three typical monsoon climate periods. The strong positive geomagnetic polarity responded to the strong rising of the Plateau and a low sea level. And the long reversal polarity was responded to the razing period of the Plateau and a high sea level. But the turning of sea level is later 0.8～1.0 Ma than the geomagnetic reversal.$$$$ |
