%X Based on the statistical data from the year 1985 to 2003,we analyzed the quantitative relationship between urbanization and total water utilization,water utilization benefits,and per capita water utilization in the Hexi Corridor,including its five districts and three major inland river basins.And the relationship model between them was constructed.Results show that,in the Hexi Corridor,the relationship between urbanization and total water utilization can be simulated by a logarithmic curve.If this condition continues,rapid urbanization in the Hexi Corridor will face up higher water stress,so the development mode of water resources and urbanization at should be adjusted,and the fresh water withdraw should be decreased step by step.The relationship between urbanization and water utilization benefits can be simulated by a linear equation.Where the urbanization and industrialization level is higher,the water utilization benefits are higher.So the Hexi Corridor should accelerate the process of urbanization and industrialization to obtain higher water utilization benefits.The relationship between urbanization and per capita water utilization is complex,but it obviously relates to the total quantity of water resources.We also found that scarce water resources obviously restricted the process of urbanization in the Hexi Corridor.And the water resources constraint intensity is the biggest in the eastern part,where water resources are the scarcest.The process of urbanization is faster in the middle part than in the eastern.However,the middle part consumed much more water resources.The western part has the highest urbanization level and water utilization benefits,but its per capita water utilization is also the highest.Therefore,the Hexi Corridor should construct an intensive water resources utilization system to lessen the water resources constraint on the process of urbanization.It is also an important task to carry out the strategy of urbanization and the great development of west China.
