Abstract Water resources shortage problem in Minqin County has attracted a lot of academic attention. The water resources ecological environment stress is defined as stress pressed on water resources in quantity and quality in order to protect ecological environment and to maintain the operation of entire socio-economic activities. In this paper, the water resources press indicator system was built from three aspects of population, economy and ecology. Results showed that water resources pressure in Minqin County was extremely high and the ecological water resources was occupied by the population and economic development, water resources were in severe shortage and the ecological environment was deteriorating. The index of water stress has fallen from 0.627 in 2000 to 0.329 in 2009 by adopting water saving, water transfer, water diversion, and other measures for many years, and water pressure had been relieved. However, the water shortage problem was not yet alleviated fundamentally; ground water was seriously overexploited and water resources for ecological environment improvement were in bad shortage.
