摘　　要：以鄂温克族自治旗为研究区域,基于1995-2010年的自然和社会经济数据,利用主成分分析法对其进行生态脆弱性评价,研究其生态脆弱性的动态变化及驱动因子。结果显示:1995年至2010年间,研究区生态脆弱性指数由-0.878 98增长至0.699 19,其脆弱性等级由轻度脆弱发展为中等脆弱,并有进一步恶化的趋势;造成鄂温克族自治旗生态环境脆弱的主要驱动力是其恶劣的生态环境背景情况以及不合理的产业发展结构和较低的社会发展水平。在此基础上,提出了研究区生态脆弱性调控对策,以期为鄂温克族自治旗生态环境和社会经济的可持续发展提供参考。Ewenki County, located at the northeast part of Inner Mongolia, has been considered as one of the most significant ecologically protective screen of north China. At the same time, Ewenki County is also a typical ecologically vulnerable area. This study assesseed the dynamics change of vulnerability of Ewenki County by using principal component analysis based on the natural and social data from 1995 to 2010. The results demonstrated that the ecologically vulnerable index of Ewenki County increased from --0. 878 98 to 0. 699 19, indicating that the ecological vulnerability of the test area developed from mild level to medium level, and the ecological environment of Ewenki County is becoming even worse. Primary reasons leading to the vulnerability of the ecosystem of Ewenki County included abominable environment, illogical industry structure as well as slow social development. This paper therefore aimed to provide guidance for the natural and social sustainable development of Ewenki County by adjusting the ecological vulnerability.
