| 摘 要： | 应用生态足迹方法和能值理论探讨了区域生态安全评价问题,提出了生态压力指数概念及计算方法,计算了山东省长岛县2003-2008年间的生态足迹、生态承载力、生态赤字、生态压力指数。分析表明,生态占用和生态承载力均呈上升趋势,生态赤字明显,生态压力指数呈上升趋势。目前长岛县生态安全等级属于Ⅳ级,处于不安全状态,生态需求与生态供给矛盾日益突出。运用改进的生态足迹方法评价区域生态安全,增强了评价的客观性、准确性和尺度性。提出的区域生态安全评价方法为长岛县生态安全管理提供科学依据和指导。

| Abstract: | This article is an elementary exploration and practice of applying emergy theory and ecological footprint to assess regional ecological security.The ecological footprint,carrying capacity,and ecological deficit of Changdao county were calculated.Furthermore,the concept and model of ecological footprint pressure index(EFPI) as well as the grade system of regional ecological security was put forward based on ecological footprint so as to analyze the regional ecological security.From 2003 to 2008 the per capit... |
