How much water resource pressure is jointly determined by demand and water supply conditions? How much role and influence does the demographic factor play? What is the relationship between the demographic factor and the other driving factors? An in-depth study has a very important significance because the above issues directly related to the future policy formulation with population, economic and resources. Based upon analysis of water resource pressure changing trend in Beijing,the driving factors of the usage of water resources from 2001 to 2010 were analyzed using the LMDI decomposition method. Furthermore, the status and role of demographic factors (including population size,household size and so on) and other various driving factors were studied. The results are shown below: The water resource pressure is not only high, but also continually rising year by year; the greatest growth driving factor of the water usage is GDP per capita growth; the demographic factor (including population size,the amount of family and household size and so on) has some influences on the changes of water usage, but it is not the main factor. Improvement for the utilization of water resources in the productive sector and proper guidance for a rational consumption view are very important to alleviate the water pressure and improve the population carrying capacity.
