太阳驱动地球环境变化研究进展

太阳是地球表层系统最重要的能量来源，地球表层环境变化记录中含有太阳辐射变化或太阳活动的印记，实际观测的太阳辐射变化却被认为不足以引起地球气候系统的剧烈变化，不同学者发展了多种物理模型来解释太阳驱动地球环境变化的机制。本文从地质记录入手，综述了太阳影响不同时间尺度气候变化的地质CD*2]生物记录，评述了几种放大机制，发现这些物理模型在解释某种气候现象时具有很好的适用性，但在其他方面也往往存在一定缺陷。我们认为：太阳变化是驱动地球环境变化的最根本因素；地球环境变化可能直接响应太阳变化。要么太阳活动引起的辐射量变化在气候系统中的作用被低估，要么还有未被发现的新机制，未来的研究应该针对这两个问题展开。

The Progress in Study of the Effects of the Solar Variation on the Earth Environment

As the most important energy source of the earth surface system, the sun influences the earth environment intensively. The records of climatic change contain much information about the change of solar radiation and solar activities, but the actual observation of solar radiation change is not considered enough to cause the earth’s severe climate change directly. Many physical models were developed to explain the mechanism about how the sun drives the earth’s environment change. These physical models have good applicability in explaining some climate phenomena; however, there are still some limitations in other aspects. Starting with the geologic records, this article reviewed the geological biological records of effects of the solar variation on the climate change on the different time scale and made comments on some JP2]amplification mechanisms. Meanwhile, we consider that the solar variation is the most important factor of the earth’s environment change; the earth’s JP]environment changes may response the solar changes directly. Either radiation changes caused by solar activities are underestimated, or there are undiscovered mechanisms. Future research should address these two issues.
