中文摘要	生态足迹是某地区生产消费的粮食和纤维、维持能源消费以及建筑用地的总和.应用生态足迹分析,共和县2002年人均生态足迹供给1.056hm2,即生态承载力阈值为1.056 hm2.该地区的人均生态足迹为1.662 hm2,与生态承载力比较,生态赤字0.606 hm2.共和县荒漠化发展是生态足迹扩大的结果之一,另一方面荒漠化扩张减小了共和县的生态承载力,因此荒漠化发展对共和县生态赤字起到两个方面的作用.提出共和县减少生态赤字,走可持续发展道路的政策措施.引入产量因子的地区修正因子,使Wackernagel因子更符合中国不同地区的实际.
英文摘要	Footprint framework offers a natural capital appraisal for nations with which human demands can be compared with nature’s available supply for human use. The ecological footprint compares renewable natural resources consumption with nature’s biologically productive capacity. A county’s footprint is the total area required to produced the food and fibres that county consumes, sustain its energy consumption, and give space for its infrastructure. In the case of Gonghe County of Qinhai Province, the average citizen occupies 1.662 hm2 of biologically productive space, while there is 1.056 hm2 available, the national ecological deficit is 0.606 hm2 per person. Desertification is a double-bind of ecological deficit for both the result of footprint expansion and the lost of biologically productive capacity. Using the range of economic and regulatory instruments available, government policies can reduced the ecological deficit by addressing the four issues. Without any doubt, the calculations presented in this study are still characterized by many limitations. One is the data source. United nations statistics may not be complete and consistent among countries or over time. The accuracy of the assessment would profit from more detailed productivity assessments, particularly for animal products and forests. Methodologically, the assessments could be made more complete by including the ecological spaces used for freshwater use, the absorption of still left out waste products and contaminants.
