摘要
采用生态足迹分析方法,即通过对生态足迹需求与生态承载力的比较,对天津市2003年生态足迹,主要包括生物资源消费、能源消费和贸易调整3个部分进行计算,评价研究了天津市可持续发展状况。结果表明:人均生态足迹为1.8391 hm2,人均生态承载力为0.5601 hm2,人均生态赤字为1.279 hm2,万元GDP的生态足迹需求为0.6958 hm2,远远低于全国平均水平(2.04 hm2)。生态赤字的存在反映了人类活动超过了生态系统的承载力,并且提出了4条改进天津市生态赤字的措施。
By using analysis on ecological footprints through comparison of ecological footprint need and ecological capacity, the Tianjin ecological footprints including the biotic resource consume, energy consume and trade regulation were computed to evaluate the sustainable development of Tianjin in 2003. Results shows that per capita ecological footprint is 1.839 1 hm^2, per capita ecological capacity is 0.5601 hm^2, per capita ecological deficit is 1.279 hm^2. The ecological footprint need of 10 thousands yuan GDP is 0.695 8 hm^2, being greatly lower than the national average levels （2.04 hm^2）. The extension of ecological deficit indicates that the human＇ s activities have gone beyond the capacity of its ecosystem. 4 measures are expended for improving Tianjin ecological deficit.and that the development of Tianiin is pushed into an unsustainable state.
