To scientifically evaluate spatial equilibrium level of water resources in Beijing-Tianjin-Hebei Region and practically improve the level of coordinately developing water security in the three regions, the integrated water scarcity amount and water scarcity ratio in each evaluation unit are calculated through analyzing the relationship between supply and demand of water resources inside and outside the river course, above and under the ground, and the water resources spatial equilibrium status in Beijing-Tianjin-Hebei Region is evaluated with water resources spatial equilibrium index. The evaluating results indicate that the water resources spatial equilibrium status of Beijing-Tianjin-Hebei Region is imbalance currently. In six evaluating units including Cangzhou and Hengshui, such situation is very serious. The status of water resources spatial equilibrium in Beijing-Tianjin-Hebei Region is getting better as long as water transfer and water saving projects are carried forward. Based on the evaluating results, water resources balanced regulation measures are proposed from the supply and demand perspectives, which consist of fixing upper limit, reinforcing water saving, retrograding improper water consuming, guarding ecology water using, increasing water supply by multiple channel and perfecting the legal system.
