| 生态足迹方法目前被广泛地应用于区域生态安全的研究中。该文通过生态足迹方法对宁夏回族自 治区1985-2005年的人均生态足迹、生态承载力、生态赤字以及生态安全情况进行分析，结果表明:宁夏 20年间人均生态足迹增长了近3倍，人均生态承载力减少率为29.60%。生态压力指数由0.6469上升到 3.5508，增长了4.49倍，生态安全等级由1985年的Ⅱ级变为1990年的Ⅳ级，此后15年生态安全等级始终 为Ⅳ级，处于极不安全状态。 |

| Abstract: |
| The method of ecological footprint has been widely applied in studying on the regional ecological safety. This article， using the method of ecological footprint， analyzed per capita ecological footprint， ecological capacity， ecological deficit and ecological safety during 1985-2005 in Ningxia Hui Autonomous Region. The results showed that the per capita ecological footprint of Ningxia increased by 3 times during 20 years， while the per capita ecologi- cal capacity decreased 29.60%. Ecological pressure index of Ningxia increased from 0.6469 to 3.5508， in- creasing by almost 4.49 times. The grade of ecological security changed from gradeⅡ in 1985 to gradeⅣ in 1990， and always kept gradeⅣ from1990 to 2005， which showed an extremely unsafe state. |
