基于生态足迹模型的南京市可持续发展研究

Sustainable Development Study on Nanjing City Based on Ecological Footprint Model

利用生态足迹模型,对南京市1995-2007年的生态足迹和生态承载力进行了定量研究。结果表明,南京市人均生态足迹逐年增加,13年间增长了63.28%,而可利用人均生态承载力逐年下降,人均生态赤字不断增加,从1995年的2.383 4 hm^2/人增加到2007年的4.368 7 hm^2/人,13年间增加了83.30%,说明南京市处于不可持续发展状态。

By using ecological footprint model,the ecological footprint and bearing capacity of Nanjing City in 1995-2007 were studied quantitatively.The results showed that the ecological footprint per capita of Nanjing City was increased year by year and totally increased by 63.28% in recent 13 years,but its available ecological bearing capacity per capita was decreased year by year.Its ecological deficit per capita was increased continuously,from 2.383 4 hm^2 per capita in 1995 to 4.368 7 hm^2 per capita in 2007,and by 83.30% in recent 13 years.It was indicated that Nanjing City was in non-sustainable development state.
