Abstract: Ecological footprint is a method for measuring the degree of sustainable development, which can be used to judge in quantity whether a regional ecological environment is under sustainable development status. Based on this method, the sustainable development status of ecological environment in Guangxi Province in 2003 was estimated, and the results showed that the per capita ecological footprint of Guangxi in 2003 was 1.1378 hm², and the per capita ecological capacity was 0.5753 hm². The resources demand was already exceeded their load, and the per capita ecological deficit was up to 0.5625 hm², suggesting that the ecological environment of Guangxi Province was in an unsustainable state, and corresponding countermeasures should be taken.
