摘要/Abstract

摘要： 白堊紀是地質(zhì)史上一個典型的溫室氣候時期，國際上圍繞白堊紀氣候成因開展了一系列模擬研究。在評述白堊紀古氣候模擬的基礎上，討論了氣候模式的應用和發(fā)展、古氣候邊界場設置和模擬試驗，分析白堊紀溫室氣體、古地理、古海洋以及海陸生態(tài)系統(tǒng)對氣候的作用和反饋。這些古氣候模擬試驗鎖定在氣候變化的關鍵時段和驅(qū)動因子、測試地球內(nèi)外動力和地球各圈層反饋作用，可為認識溫室氣候的成因、探討氣候變化內(nèi)在機制和預測未來氣候提供重要的科學依據(jù)。

關鍵詞: 白堊紀, 溫室氣候, 古氣候模擬, 驅(qū)動機制

Abstract: The Cretaceous is a typical period for greenhouse climate in geological history and has become an important paleoclimate simulation period in international paleoclimate modeling community. This paper reviews a series of Cretaceous climate simulations, discusses the climate model's developing, the paleoclimatic boundary conditions and the experiment designs, and analyzes the impacts and feedbacks of atmospheric greenhouse gases, topography, oceans and terrestrial ecosystems on the Cretaceous climate system. These simulations focused on the major factors driving Cretaceous climate changes and the critical time periods of the climate change, and tested the internal and external forcing in the earth climate system and the feedback effects among various spheres of the earth system, thus providing us an understanding of the mechanism of greenhouse climate and an important scientific basis for projection of the future climate changes.

Key words: the Cretaceous, greenhouse climate, paleoclimate simulation, driven mechanism
