In this research,we briefly reviewed the research process on climate change adaptation. It is revealed from our review that the insufficient scientific understanding on adaptation is a bottleneck for the wide deployment of adaptation actions,thus the scientific support on climate change adaptation actions would be greatly enhanced. Combining the new international environment under the Paris Agreement framework and the domestic situation,it is investigated the overall speculations,principles,aims,and the prospect on the science and technology development of climate change adaptation,as well as the mechanisms for climate change adaptation innovation.
