中文摘要：

应用生态足迹模型,对黄土高原各省区2004年资源消费现状进行了实证的计算和分析,分别得出各省的人均生态足迹、生态承载力、人均赤字、适度人口等指标。结果表明,内蒙古处于可持续发展状态,但对草地和水域的需求仍然较大;其余各省生态赤字巨大,这些省的土地供给已远不能满足人们对土地的需求,均处于生态不可持续发展状态;河南和陕西的人口超载率较高。对黄土高原各省区生态赤字存在的主要原因及生态足迹模型计算中存在的问题进行了讨论。

英文摘要：

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 2004 through large amount of data collection and calculation.At the same time,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 now in 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 forward simultaneously for the realization of regional sustainable development.Meanwhile,the problems of the ecological footprint model which need to be noticed are briefly discussed.
