Abstract: Based on daily air temperature, precipitation data in Chaoyang city during 1961-2016, and socioeconomic statistics data from 2007 to 2016, the evaluation system of urban adaptability to climate change including climate and urban subsystem was constructed with the analytic hierarchy process (AHP) method.The adaptive ability is divided into five levels according to the comprehensive index, and the membership degree of climate risk, city adaptation, comprehensive adaptability were dynamically assessed during 2007-2016.The result shows that the risk of climate subsystem increases significantly from a "little low" to a "general" level, which is attributed to the increases in disasters and extreme climate risks.With the development of the urban economy and the improvement of public services, the adaptation of the city subsystem is constantly improved from a "low" level to a "high" level.Under the combined effect of climate and city, the comprehensive adaptability of Chaoyang increases obviously from a "little low" to a "little high" level with a rate of 0.029/a in the past ten years.
