中文摘要：
近十几年来,地球系统模式领域活跃着一类新兴的模式——中等复杂程度的地球系统模式（EMICs）,EMICs以其对计算能力的较低要求和对地球系统的较为完备的描述,使其应用几乎覆盖了简单模式和大气环流模式（CGCMs）的所有研究领域,特别在长期气候变化的模拟方面展现了得天独厚的优势,从而使得在长期气候变化的背景下研究近代气候变化更具现实意义。EMICs已经成为模拟地球系统的有力工具,为目前的CGCMs模拟提供了必要的补充,在简单模式与CGCMs之间架起了一座桥梁。首先回顾了中等复杂程度地球系统模式（EMICs）的发展现状,结合近年来国内外发表的文献探讨了EMICs的基本组成、应用领域,并对EMICs未来的发展趋势进行了预测。
英文摘要：
In recent decades, except for conceptual and three-dimensional comprehensive models （CGCMs）, Earth system models of intermediate complexity （EMICs） as a new type of models occur in the scope of the Earth system models. EMICs simulate the interactions among several or even all components of the Earth system explicitly, albeit in a more reduced, i. e. , more parameterized form. Thus EMICs describe the Earth system in an almost complete manner. Just due to their Simplicities, EMICs need more low Computation cost. Therefore, EMICs can not carry out only long-term simulations over 10 000 years, but a broad range of sensitivity experiments. EMICs have already become an integrated and powerful assessment tool for environmental studies, and bridge the gap be- tween present CGCMs and conceptual models. In this review paper, status and improvements of EMICs are reviewed firstly. Then based on the domestic and foreign published literatures, the basic composition and application domain of EMICs in recent years are discussed. Finally, the future development trend of EMICs is forecasted.
