The urban climate carrying capacity,as the core measure of the city's adaptation to climate change,reflects the mutual feedback relationship between the urban system and the climate system. Its spatial status is related to urban security and sustainable development. Based on DPSIR and state space method,construct the urban climate-bearing space conceptual model,the climate carrying capacity evaluation index system and evaluation model,and build a Climate Capacity-Spatial Adaptation method system; combine GIS with Xiamen as the concrete case city for urban climate capacity space simulation analyze in qualitatively,quantitatively, and locally,create a UCC map,determine Climate Capacity-Spatial Adaptation hotspots,and propose Climate Capacity-Spatial Adaptation optimization recommendations. To supplement the " climate change" and " urban space" to adjust the gaps in the adaptation, to provide technical support for China's cities to actively respond to climate change.
