Adaptation to climate change is an important measure to cope with climate change problems at present. Critera for identification of adaptation to climate change are the foundation to draw up lists of adaptation technologies, which are the important component of methodology on adaptation to climate change. Based on the analysis of climate change and its impact, the connotations of climate change problems that human face are identified. According to the definition of climate change, the core criterion for identification is confirmed, which is the pertinency of climate change problems. The key rests with how to distinguish the adaptation aspect from routine aspect of technologies. On the other hand, adaptation technologies and mitigation technologies are compared. It is an important criterion to discriminate between mitigating effects and adapting effects. According to the above critera, the existing adaptation technologies in different regions and different fields can be recognized and selected. It can provide guidance for the research on adaptation technologies to climate change in future, and establish a solid base for constructing the technology system of adaptation to climate change.
