The Beijing-Tianjin-Hebei Region has low per capita water resources, high water use pressure, and prominent water resources problems. Therefore, it is urgent to carry out a comprehensive evaluation of water resources carrying capacity in this area in order to provide some theoretical basis and practical experience for the comprehensive planning and efficient utilization of water resources, regional sustainable development, and so on. This study first analyzed the background of water resources utilization in the Beijing-Tianjin-Hebei Region and the water resources problems faced by the region; second, based on the analysis of water resources system, a comprehensive evaluation index system of water resources carrying capacity in the region based on quantity-quality-water bodies-flow was established; finally, the analytic hierarchy process (AHP) and entropy weight methods were used to combine subjective and objective weights of evaluation indices, and the TOPSIS evaluation model was used to calculate the comprehensive score of water resources carrying capacity. The results show that: (1) The overall lack of water resources, the over-exploitation and utilization of water resources, and the continuous overexploitation of groundwater in the Beijing-Tianjin-Hebei Region have resulted in the loss of water ecological functions and the formation of concentrated and connected groundwater funnel areas; (2) The comprehensive evaluation scores of water resources carrying capacity in 2006-2016 show a fluctuating growth trend, indicating that the carrying capacity of water resources has been strengthened, but the total score is generally low and the pressure on water resources is grim. Based on this situation, the Beijing-Tianjin-Hebei Region urgently needs to build regional and watershed water resources linkage mechanisms, and take the Beijing-Tianjin-Hebei collaborative development policy as an opportunity. According to the conditions and position in the regional development plan of different cities, urban development and industrial production should consider water resources endowments, implement the most stringent regulations on water resources management, and finally achieve the improvement of regional water resources carrying capacity.
