摘要
生态足迹是近年来广泛运用于评价区域发展可持续性的重要方法。基于生态足迹计算模型,对安徽省池州市2001—2010年生态足迹进行测算,并选取了社会经济相关指标,运用主成分回归方法,基于STIRPAT模型,构建了影响生态足迹增长的驱动力因子模型。研究结果表明,池州市人均生态足迹均呈上升的趋势,且生态足迹的需求远远大于生态承载力,出现了生态赤字,且有进一步扩大的态势,表明池州市处于相对不可持续发展的状态。驱动机制分析模型表明,池州市工业经济发展对人均生态足迹增长具有强烈的驱动作用。近年来,随着池州市工业化进程的加快以及"工业强市"战略的大力实施,工业经济规模不断扩大,都极大地推动了生态足迹的增长和生态赤字的扩大。
Ecological footprint is a newly prevailing approach to evaluate the sustainability of regional devel opment. The ecological footprint for Chizhou City, Anhui Province, from 2001 to 2010 was calculated using ecological footprint model and then some socioeconomic indicators were selected and analyzed by principal component regression method. Based on the STIRPAT model, an ecological footprint driving factors model was further constructed. The trend of ecological footprint per capita moved upward and ecological footprint demand was far greater than ecological capacity. Ecological deficit appeared and expanded. This indicates that Chizhou City was in the status of relatively unsustainable development. Besides, the driving model re flects that the development of industrial economy was a strong driving force for ecological footprint. With the industrialization process speeded up and the strategy of ＂strong industrial city＂ energetically carried out, the scale of industrial economy expanding, the growth of ecological footprint and the expansion of ecological deficit have been strongly enhanced in Chizhou City.
