本文概述了气候变化综合评估模型（IAM）的定义、组成、特点及应用。IAM可视为一种促进人类更好地理解气候变化问题的工具，它为研究者和决策者提供了一种十分有益的关注环境问题的框架或方法论。

This paper presents a brief introduction of integrated assessment models (IAM) of climatic change. Then the Integrated Model to Assess Greenhouse Effect 2.0 (IMAGE2.0), a multi disciplinary, integrated model designed to simulate the dynamic of the global society-biosphere-climate system and to evaluate consequences of climate policies is introduced. This suggests that IAMs are useful tools so far to quantify as much as possible the cause effect relationships of the climate change problem and the cross-linkages and interactions between diverse issues concerned. Chinese research community should pay more attention to the development of IAMs so as to broaden our understanding of climatic change and to aid the decision making process about influences of human activities on environmental and climatic change.
