Based on the data from the communiques of water resources in Fujian Province (1999 -2009), this paper discussed the trend and driving forces of water consumed structure in Quanzhou city of Fujian Provingce. The results showed that Quanzhou''s water consumed structure presents the change of "one decreasing one increasing and one stablilizing", that is, agricultural water continuesly declined, the proportion of industrial water rised,and life-water relatively unchanged. The main cause of this trend is the process of Quanzhou''s industrialization and urbanization. The change of the industrial structure increased the industrial water consumption and proportion. At the same time, the proportion of agricultural water decreased. Population growth and expansion of urban land in the process of urbanization increased the life-water consumption, which also reduced the agricultural water consumption and proportion.
