摘要
应用生态足迹模型对宁夏回族自治区固原市生态经济系统的可持续发展状况进行定量测度。结果表明固原市2002年人均生态足迹需求为1.892 5 hm2,而当年实际上可以提供的人均生态空间面积为1.259 2 hm2,人均生态赤字0.633 3 hm2。生态足迹需求超过了生态足迹供给,出现生态赤字,则区域生态环境处于不可持续状态。
The quantitative determination was conducted on sustainable development condition of ecological and economic system in Guyuan city of Ningxia Hui autonomous district applying ecological footmark model. The result showed that： the requirement is 1. 892 5 hm^2, of average ecological footmarkper person in Guyuan city in 2002, whereas the practical average ecological space area is 1.259 2 hm^2, provided in the same year for per person, the average ecological deficit is 0. 633 3 hm^2. The requirement of ecological footmark exceeds its provision and appears ecological deficit, so the ecological environment is the condition of unsustainable development.
