摘要
工业革命后,人类活动影响地球环境达到了空前的程度。近年提出的人类世(anthropocene)概念就是为表征地球系统演变进入了这一特殊的新纪元。然而,人类活动并非单向地影响自然,它在改变自然环境的同时,环境变化也影响着人类行为,迫使人类去适应自然变化,改变生存方式。为更深入地表征人类活动与地球环境相互作用的这种特征,作者讨论了在地球系统模式里引入"人类圈(anthroposphere)"的必要性以及由此带来的新的科学挑战,并提出了构建包含人类圈的地球系统模式的一些思路。
A new concept,‘anthropocene’ , was proposed in recent years to emphasize that the Earth environment entered a new epoch in association with the Industrial Revolution, when human activities became able to influence the Earth environment at a global scale. However, human activity not only influences the environment, but also adapts itself to the changing natural surroundings. In order to characterize the interaction between human activity and natural environment, it is necessary to induce an interactive ＇anthroposphere’ in the Earth system model. Challenges in association with construction of the Earth system model including this new component are discussed.
