Water resources are a favorable guarantee for the economic and social development of a region. Utilization efficiency of water resources is of great significance for formulating rational water resources strategy. In this paper, a gray target model is weighted by the synthesized integration weight method which combines the order relation and the entropy weight. Through the construction of evaluation index system for sustainable utilization of regional water resources, the comprehensive evaluation of water resources utilization in Beijing-Tianjin-Hebei region in 2016 was carried out. The results show that: (1) the water consumption structure of Beijing and Tianjin is relatively balanced, while Hebei Province shows typical characteristics of agricultural cities. The agricultural water footprint accounts for more than 90% of the total water footprint, followed by residential water, industrial water and ecological water. (2) In 2016, the total water footprint of Beijing-Tianjin-Hebei region showed a distribution pattern with Beijing as the center, surrounded by all sides, and the distribution pattern of the center was high and low. The sustainable utilization level of water resources concentrates on the middle and poor grades, and there is still room for improvement.
