Ecological Carrying Capacity

To improve the ecological footprint model in aspect of reflecting sustainability of the economic, social and technological, the emergy analysis and socio-economic system development index were introduced into the model. The modified ecological footprint model was applied in the calculation of ecological carrying capacity and ecological footprint in Tibet, China. The ecological carrying capacity/cap is 19.13hm2, and the ecological footprint/cap is 8.96hm2. The result shows that the Tibet region is under the condition of ecological surplus and it is suitable for further programs development to some extent. But the high proportion of energy resources, cement and fertilizer utility should draw attention during the exploitation or construction progress.

Development Assessment

Based on the survey on deficiencies of ecological footprint model applied on regional sustainable development assessment, modification of the ecological footprint model was preliminarily discussed on three aspects: concept extension, combination with other index, and introduction of quantitative estimate indices for time series calculation. This discussion provided a scientific guidance of applying ecological footprint model on regional sustainability assessment, and a theoretical basis for further case study.
