| Abstract: |
| The ecological footprint model initiated by William E．Rees and Wackernagel Mathis is adopted to verify provincial sustainable development condition on the Loess Plateau in 2004through large amount of data collection and calculation. At the same ti me provincial resources consumption are calculated and analyzed including average ecological footprint ecological capacity ecological deficit and moderate demographic indicators． The result shows that Inner Mongolia is in the sustainable development state though there is a larger demand at grassland and water area. While an obvious ecological deficit exits at the remaining provinces separately. It means current land supply of these provinces can not meet the demand for land so these provinces are nowin an unsustainable ecological development state. Population of Henan and Shaanxi have the higher overloading rate compared with others. Finally according to the calculation results the main reasons of ecological deficit existing for these provinces are to be identified and analyzed for future development. Also specific proposals are set for ward si multaneously for the realization of regional sustainable development. Meanwhile the problems of the ecological footprint model which need to be noticed are briefly discussed. |
