Abstract:The emergetic ecological footprint model has been considered to be a valuable and significant method for quantitatively analyzing regional sustainable development. Nevertheless, the deviated results are affected by the ecological carrying capacity, which is not accounted with the factors of economy, science and technology progress. This research introduced the virtual accounts of socio-economic development to modify the model, and took Changsha City as an example for validity check. The results indicated that the modified model, which paid more attention to the elements of eco-economic system but only the ecological component, were more reliable, accurate and reasonable than the original model. Based on the modified emergetic ecological footprint model, the annual ecological carrying capacities of Changsha City were without significant change from 2000to 2011, with the average value of 2.31hm2per capita. While the ecological footprint, which average value was 2.44hm2per capita, exhibited a trend of rapid growth and caused a gradually increase of the ecological deficit with the average value of 0.13hm2per capita. The giant pressures from the agricultural activity and the heavy industry with high-level energy consumption were considered to be the principal factors, which prompted the growth of the local ecological deficit.
