Ecological Footprint (EF) theory has an important guiding significance for urban ecosystem research and ecological construction of a city. In this paper, we report an assessment on dynamic change of EF in Guangzhou based on data from 2001 to 2005. Our results show that EF demand per capita was 3.95527 hm2·person-1 in 2005, which was much greater than supply. During 2001～2005 EF percapita tended to increase and the demand for fossil fuel EF was ranked as top one that took up 72.67% of the EF demand in 2005, while EF per ten thousand Yuan GDP tended to decrease. By the means of STELLA it is forecasted that the tendency of EF demand per capita in Guangzhou till 2025 would be going up. It is concluded that the demand for fossil fuel EF is a key contributing factor for increased demand of EF in Guangzhou.
