Abstract: Ecological footprint (EF) method was used to measure the ecological pressure in Shenyang City in 1991〖KG-*2〗-〖KG-*7〗2005, and the EF of the City in 2006〖KG-*2〗-〖KG-*7〗2010 was predicted. The results showed that in 1991〖KG-*2〗-〖KG-*7〗2005, the per-capita EF of the City was 175 hm2, while the per-capita bio-capacity was 041 hm2, resulting in a per-capita ecological deficit of 134 hm2. The per-capita EF demand was 324 times more than the bio-capacity. The cropland and energy footprints accounted for more than 85% of the total EF, and thus, the changes in these two components had substantial effects on the total EF. According to the prediction, the EF of Shenyang City would grow at a high rate after 2005, and would reach 511 hm2 per capita in 2010, being 350, 332, and 196 times of that in 1991, 2000, and 2005, respectively. Based on the outcome of this study, some suggestions were proposed for the ecological and sustainable development in Shenyang.
