【摘要】 在地球的气候史中,经历了许多次气候突变事件。这些突变对地球表层系统的演变与进化产生了巨大影响。随着全球气候变暖的持续发展,人类赖以生存的气候环境正在经历重大变化。如何科学地理解和认识这些变化,尤其是气候突变,是人类寻求对策,应对气候变化,保护自己持续发展的科学基础。文中从地球系统的角度对气候突变的科学问题进行了探讨,认为对气候突变的研究不应仅局限于大气圈,而应该对地球系统的整体变化进行研究。更多还原

【Abstract】 In the history of earth’s climate, there were many abrupt climate change events.These events had great influence on the evolution of the earth’s surface system. With the continuous development of global warming,the climatic environment,which human being lives in, is experiencing the great changes. How to understand and recognize these changes, especially like abrupt climate change, is the scientific foundation for countermeasures to climate change and keep the sustainable development on.In this paper, we discussed the scientific issue of abrupt climate change from the viewpoint of the earth system. It is pointed out that it is not suitable to understand abrupt climate change only in atmosphere, we must take it account as the change of earth system as a whole.更多还原
