摘要： According to related statistics, this paper selected 15 indicators to establish the evaluation index system of water resources carrying capacity and evaluated the level of water resources carrying capacity in Beijing-Tianjin-Hebei Region during 2004 and 2014 using the principal component analysis while comparing the water resources carrying capacity in Hebei, Tianjin and Beijing. The results show that there are four factors affecting water resources carrying capacity, including industry-environment factor, agriculture-society-water supply factor, life-ecology factor and water resources exploitation factor. During the period from 2004 to 2014, Hebei Province gets the maximum score in evaluating the water resources carrying capacity, then Beijing gets the lower level, and Tianjin gets the lowest level. The water resources carrying capacity in Hebei Province decreased in the fluctuation and increased after 2012, which rose in the fluctuation in Beijing and showed a periodic variation in Tianjin.
