Abstract: Abstract The Huaihe River basin is located in eastern and central China and in a climate transition zone. Its unique geographical location and climatic conditions have led to increases in flood waterlogging damage in the basin. The impact of climate change on water resources in the basin and the adaptability of these resources to these changes deserve attention. To achieve the objectives of climate resilient development, society and ecosystems must transform into a more resilient state. This dynamic process includes two stages: adaptation and resilience. In this study, elements of social resilience were integrated into adaptability analyses. Three aspects of the adaptation mechanism of water resource system are discussed: natural resilience, artificial adaptation, and social resilience. An index system that conforms to the process mechanism of water resource system adaptability was constructed. The fuzzy analytic hierarchy process was used to identify and analyse indexes of natural resilience, artificial adaptation and social resilience. Based on the adaptation mechanism of the water resource system and the original two-dimensional risk matrix, a method combining the connection number and three-dimensional risk matrix was established. In addition, a risk element combination table of a three-dimensional risk matrix and its chromatograms was obtained. Finally, an empirical study was conducted using the Huaihe River basin in Anhui Province, China, as an example. The results indicated that the adaptability level of the upper region of the Huaihe River basin in Anhui is higher than that of the lower region, and the adaptability level of the southern part is higher than that of the northern part. To improve the adaptability of water resource system in the lower and northern regions, targeted, evidence-based measures for strengthening water resource management in the Huaihe River basin are needed.
