区域生态安全与生态足迹对比研究——以陕北延安地区为例

文章选择延安地区为实证案例，采用生态安全与生态足迹方法评价区域发展的可持续性。结果表明，延安地区在区域尺度上处于不可持续或不安全发展态势。其中，生态安全度综合评分值为0．404，属于较不安全；人均生态足迹大于人均生态承载力，出现0．4746hm^2的人均生态赤字。同时，就实证分析过程对2种研究方法的应用特点及适用范围予以评价，以期为探讨更真实、全面、客观评价区域可持续发展的方法提供科学依据。

Contrast Study on Regional Ecological Security and Ecological Footprint——Take Yan'an Region as An Example

Ecological security assessment and ecological footprint analysis are typical methods for region sustainability development assessment.But as far as the contrast study between these two projects in methods application concerned,no outcomes have turned up.In this article,choose Yan'an region as an example,adopt the methods of ecological security and ecological footprint,and evaluate the sustainability of region development.The results show: The ecological security synthetic evaluation of Yan'an region is 0.404,belonging to insecurity;The average of ecological footprint per capita is more than that of ecological burden per capita,with the average of ecological deficit per capita being 0.4746 hm~2.Both methods demonstrate Yan'an region belongs to un sustainability or insecurity development state.At the same time,the practical characters and practicable extent of these two methods assessment has been done in order to offer more creditable,all-round,objective and scientific methods for region sustainable development.
