Water resources shortage and water environment pollution have become the major obstacles for the coordinated development of Beijing–Tianjin–Hebei region. In this paper, the status quo of and challenges for water resources regulation and water environment protection in the Beijing–Tianjin–Hebei region are analyzed, and corresponding strategies are proposed, including building a water ecological system involving mountains, rivers, forest, farmland, lakes, and sea using technical approaches; establishing a healthy recycling and efficient utilization model for water resources; developing production and living modes adapting to the carrying capacity of the water ecology; improving water environment quality and ensuring the health of regional water ecosystems; establishing a coordinated management system for the regional water environment; strengthening industry cooperation and pollution reduction; and promoting peri-urbanization and pollution abatement in the rural areas. This study is hoped to provide decision support for comprehensive ecological environment control in the Beijing–Tianjin–Hebei region and ecological civilization construction in China.
