南京市2005年生态足迹分析

采用生态足迹分析方法比较生态足迹需求与生态承载力,对南京市2005年生态足迹(包括生物资源消费、能源消费)进行计算,得出2005年该市人均生态足迹为4.488 207 hm2,可利用的人均生态承载为0.285 67 hm2,人均生态赤字4.202 537 hm2。结果显示,南京市人均生态足迹是可利用的人均生态承载力的15倍,生态赤字远大于生态承载力。这反映了南京市的生产、生活强度超过了生态系统的承载能力,城市生态系统所受压力偏大。最后,针对南京市的社会经济发展与资源的利用特征,提出了缓解南京市城市生态压力的合理建议。

Analysis of Ecological Footprint of Nanjing in 2005

Ecological footprint need and ecological capacity were compared by using the ecological footprints analysis method.Ecological footprints,including the biotic resource consume and energy consume,in Nanjing were calculated in 2005.The average per capita ecological footprint and the per capita available ecological capacity in 2005 were 4.488 207 and 0.285 67 hm2,respectively.And the ecological deficit was 4.202 537 hm2.Result showed that the average per capita ecological footprint in Nanjing was 15 times of the per capita available ecological capacity.Ecological deficit was far greater than the ecological capacity,which reflected that the production and life intensity had gone beyond the capacity of its ecosystem.The carrying capacity of the eco-systems in Nanjing was under great pressure.Finally,aiming at the character of socio-economic development and resource utilization,some reasonable suggestions were proposed to alleviate the city's eco-pressure.
