Abstract: Ecological footprint (EF) model has been widely used in evaluating sustainable development and ecological capacity (EC). Based on the statistics of Dalian City, its EF per capita and EC per capita were calculated to evaluate the ecological sustainable development of the city. In the meantime, the water footprint of the city in 2001 was analyzed by using water footprint approach. The results showed that from 1991 to 2004, the ecological footprint per capita of Dalian had an overall increase, with the mean EF being 2.250 hm2 per capita or more. The EF was 2.250 hm2 per capita in 1991 and 3.965 hm2 per capita in 2004, and there existed different level ecological deficit from 2000 to 2004. The water footprint in 2001 was 748.270 m3 per capita, being lower than the mean level of North China, suggesting that Dalian City belonged to water deficit area.
