Abstract

China has long faced the problem of uneven distribution of water resources in time and space. The state of water security is therefore a key factor in regional development. The Jing-Jin-Ji district in China includes Beijing, Tianjin, and Hebei Province, which faced severe water security problems. Therefore, to improve the management of water resources, water security should be properly evaluated. This study established a comprehensive evaluation index system for evaluation. Furthermore, this study analyzed the impacts of the South-to-North Water Transfer Project, which fully reflects the impact of human activities on the spatial distribution of water resources, which is an innovation. The results showed that the state of water security in the Jing-Jin-Ji district generally had an increasing trend, score for water security increased 65.8%. The Middle Route of the South-to-North Water Transfer Project had played a major role in water security in resources criterion, which increased 28.53% in 2015 and 13.64% in 2016. With social development, the general state of water security in the district was improving. These findings could provide a scientific basis for regional water resources management.
