摘　　要：为了进一步了解县域生态安全的基本态势和变动特征,以生态环境问题较为突出、人类活动扰动较大的汾河源头——宁武县为例,基于联合国经济合作开发署提出的压力-状态-响应概念框架,构建综合评价指标体系,以变异系数法确定权重,运用2001—2010年宁武县统计数据,通过计算生态安全综合指数,对近10年宁武县生态安全状况进行分析。结果表明:其生态安全状况由重警状态步入较安全状态,反映了宁武县生态经济系统运行在历经经济增长与生态环境尖锐对立状态之后,正在趋于不断缓和。尽管生态安全意识不断增强,却由于人口增长和经济发展的客观要求,生态安全的保证程度仍处于不稳定状态。In order to understand the status quo and changeable tendency of ecological security in county area, the author took the example of Ningwu County, the headstream of Fenhe River, confronting serious eco-environment problem and considerable human impacts. Taking Ningwu as the study area and using variation coefficient method to determine the weights of the indices, the author built ecological security pattern based on Pressure-State-Response Model of organization for economic cooperation and development. The ecological security status was evaluated by calculating eco-security index with socio-economic statistical data of Ningwu in the recent 10 years. The results showed that： the situation of eco-security had been improved from heavy alarm to relative safety during 2001-2010. It reflected that the ecological economic system in Ningwu County in which a sharp conflict between its ecological environment and its social and economic growth tends to be relaxed constantly. The ecological safety awareness was growing, however, by force of the objective requirements of population growth and economic development, the situation of ecological security was still unstable.
