地球冰期起源问题,属重大基础理论课题之一。揭示地球冰期起源奥秘,对阐明陆架发育演化进程,预言亿万人所关切的地球未来气候变异和海、陆变迁趋向具有积极意义。到目前为止,有关地球冰期起源问题,国际上还没有一致公认的假说。实际材料表明,在地球历史发展漫长的进程中,存在着冰期和间冰期的脉动交替,温暖期和寒冷期的脉动变异。笔者在本文中提出,地球冰期脉动变异韻律的产生,同太阳这个巨大天体本身辐射强度的脉动变异状态存在着重要联系。
The origin of Earth’s ice age is one of the major basic theoretical topics. Revealing the mystery of the origin of the Earth’s ice age is of positive significance for clarifying the development and evolution of the shelf and predicting the future climate change and the trend of the sea and land changes of concern to hundreds of millions of people. So far, there are no universally accepted hypotheses about the origin of the ice age in the world. The actual material shows that in the long course of Earth’s history, there are ripple alternations in glacial and interglacial periods, and pulsation variations in warm and cold periods. The author proposes in this paper that the rhythm of variation of the pulsations in the Earth’s ice age has an important connection with the pulsatile variation of the radiation intensity of the giant celestial body itself.
