地球气候变化的米兰科维奇理论研究进展

米兰科维奇理论是从全球尺度上研究日射量与地球气候之间关系的天文理论（以下简称为“米氏理论”）。该理论认为，地球轨道偏心率、黄赤交角及岁差等三要素变化引起的到达北半球中高纬度夏季日射量变化是造成冰期—间冰期旋回的根本原因。详细回顾了米氏理论的发展历程，并以南极东方站过去42万年大气和气候变化的历史资料为例，讨论了经典米氏理论中有待研究的若干问题。

Progresses in the Milankovitch Theory of Earth's Climate Change

Milankovitch has proposed an astronomical theory to explain the relationship between solar insolation and the Earth's climate.It postulates that the changes in insolation at the Northern Hemisphere during the summer months,which are caused by changes in Earth's eccentricity,obliquity and precession,are mainly responsible for driving the glacial-interglacial cycle.In this paper,we reviewed the development process of the Milankovitch theory and its progresses in some detail,and discussed several scientific issues that need to be investigated further by taking the climate and atmospheric history of the past 420 000 years from the Vostok ice core,Antarctica,as an example.
