摘　　要：2015年出版的《第三次气候变化国家评估报告》总结了第二次评估报告发布以来中国学者对气候变化影响与适应的最新研究结果.科学界对中国气候变化影响与适应研究的主要认识进展有:不同领域(农业、水资源、生态系统、冰冻圈、海岸带等)和区域已经显现出来气候变化影响的事实,总体判断弊大于利,特别是未来进一步增温将主要造成负面影响.影响评估的特点包括,气候变化对重点领域影响评估更加全面,重点领域对气候变化响应过程研究深入,评估方法与数据更加规范,辨识气候变化对不同领域和区域影响的利弊.本文分析了气候变化影响与适应研究差距.未来的研究将集中在降低气候变化影响认识的不确定性、提高定量化风险评估水平、增强气候变化影响与风险的综合交叉、趋利避害适应原则、有序适应机制、定量适应措施.The target of average global 2℃ warming compared to pre-industrial times was agreed by more than 100 countries, and was adopted at COP 21（21st session of the Conference of the Parties） to the UNFCCC（United Nations Framework Convention on Climate Change） in 2015. However, even if the INDCs（Intended Nationally Determined Contributions） for 2025 and 2030 could be fully implemented in the future, a warming of around 2.7℃ at least above pre-industrial would appear before 2100, which will result in negative impacts and risks for agriculture, natural ecosystem, socio-economic system, etc. Therefore, assessment on the climate change impacts and application of adaptation measures against climate change risks have been commonly accepted by the governments, scientific communities and international organizations. The newly-published Third Assessment Report of the Chinese Climate Change had assessed the newest findings about the impacts and adaptations of climate change in China, which was continually studied by Chinese scholars after the second assessment report. Most researchers have reached a consensus that the impacts of climate change had emerged in different fields（such as agriculture, water resource, ecosystem, cryosphere, and coastal zone） and areas of China. Climate change impacts have pros and cons, while the disadvantages outweighed, especially for the further warming under climate change scenarios. The characteristics of the impact assessments include： the assessment on the impacts of climate change on the key sectors are more comprehensive, the studies on the responding processes to the climate change for important sectors are more thorough, the assessing methods and data are more standardization, the pros and cons of climate change impacts were identified for different fields and areas. And then, this article analyzed the research gaps for the studies on the impacts and adaptations of climate change. Although several studies were entitled as ‘climate change impact＇, the influencing mech
