文摘The development of urbanization has a close relationship with fresh water resources, especially in the rapid urbanization period. By analyzing the course of the urhanization development and the experience of international urbanization development, the paper confirms the starting time of the rapid urbanization. Based on the ecotogical theory; urban fresh water consumption is composed of three types： the direct, the indirect and the induced water consumption. And the paper constructs calculation model of the indirect and the induced water consumption. Using the related statistics data, the paper makes an empirical research on the changes of the amount and structure of water consumption. Then it discusses the correlation between the water consumption and the amount of urban population, and the result shows that the amount of the water consumption arid the urban population have a remarkable correlation with the exception of the amount of the indirect water consumption, and the curves fake on quadratic functian form. Last, from the urban fimction point of view; the paper anatomizes the cause of the urban water consumption changes.
