It is recognized that large amount of population migration and urbanization would bring impacts on regional environment. These impacts may cover many aspects, such as water use, energy consumption, land use change and pollution, etc. This paper focuses on domestic water use issue as an example.<BR>Firstly, the mechanism of population migration is examined by using both nationwide time-series data and 2000 Census data.
