Abstract:[Objective] Assessment of the vulnerability of water resources in Beijing-Tianjin-Hebei(BTH) region was carried out in order to provide theoretical and data support for water resources management.[Methods] This study focuses on the vulnerability of water resources in BTH, a highly populated and developed region yet with serious water resource problems. An indicator system of water resources vulnerability was established by integrating resource pressure, development pressure, pollution pressure and management pressure(RDPM) using the concept theories of water footprint while analytic hierarchy process was used to determine the weights of different indicators. Then the water vulnerability was assessed from 2003 to 2013 for the BTH region.[Results] The BTH region was exposed to problems such as poor water resources endowments, high water exploitation, serious water pollution and unbalanced management. Beijing City had a relatively high level of water resources management, it still suffered from serious water pollution. Tianjin City has made a great progress in water resources management, but the water resources vulnerability did not show a declining signal and new management approaches need to be explored. Compared to Beijing and Tianjin City in terms of water resources management, there is a big lag in Hebei Province, whose water resources vulnerability seems to be more serious in these years. As a result, Hebei has been a "short slab" of water resources management in the BTH region.[Conclusion] It is imperative to relieve the pressure on water pollution, increase the management strategies in Hebei Province, allocate water resources reasonably and improve water management in all BTH regions.
