Abstract: Water pressure model of oasis city was built to evaluate the change of water resources pressure indexes in Urumqi City,Xinjiang,China from four aspects as population pressure,ecological pressure,economic development pressure and technical pressure,and then the impact of water shortages on urban development was analyzed. The results show as follows:(1) the composite stress index of water resources in Urumqi showed a rapid growth trend,which rises from 0.32 of 1995 to 1.08 of 2012. The main reasons are the deterioration of water resources,the rapid growth of population and the difference in water quota with developed areas. (2) Per capita water resources of Urumqi continued to decline,which was 729.54 m3 in 1995 and 377.8 m3 in 2012,with 48.21% of decreasing. It was transferred from moderate to severe shortage of water resources,and the ratioes of water resources exploiting and utilization were over 100% after 2009,which affects significantly on urban expansion and hinders the growth rate of urban economic development. (3) Strengthening water management capacity,accelerating intensity of water-saving,implementation of inter-basin water transfer,and industrial restructuring were effective to ease the pressure on water resources and promote cities to healthy development.

Key words: water resources, pressure index, urban development, oasis city, Urumqi
