Human is dependant on biosphere, which provides steady supplies to human life, including not only economic activities and resources used on life, ecological aggradations capacity of assimilating waste materials, but also many non consuming life supporting services This consumption and affecting extent of human activities on natural ecosystems is called “Ecological Footprint(EF)” EF is a new prevailing method to quantify the stress on natural ecosystems from human activities in recent years To introduce EF analysis into urban ecosystem research is a new idea and direction, for it can quantify the pressure and effect of urban economic activities on natural ecosystems, by which we can judge the health situation of urban ecosystems Numerous papers dealing with EF have been published in China in recent years, but few of them on urban EF studies This paper estimated the present EF and analyses the trends of change in the past 5 years by taking Guangzhou city as a case.The results indicated that, Guangzhou's EF and carrying capacity in 2000 are 2.5 ha/cap and 0.2 ha/cap respectively And during 1995 2000 EF per ten thousand yuan GDP tends to decrease, while EF per capita tends to increase This shows that Guangzhou economic development model is transferring from extensive to intensive, but policy makers should focus on improving use efficiency of resources, calling for saving pattern in human production and consumption, and trying lessening EF in the future ecological construction, which can make Guangzhou step toward eco city and achieve sustainable development
