摘要
利用生态足迹模型对四川省1993-2002年的生态足迹进行了计算与分析.结果表明:四川省的人均生态足迹成增长趋势,人均生态承载力成下降趋势,人均生态足迹已经超过人均生态承载力,出现生态赤字,并持续扩大,四川省目前的发展处于一种强不可持续状态.最后根据定量测评结果分析了造成生态赤字的原因并提出了降低生态赤字,实现四川省可持续发展的措施.
The ecological footprints and ecological capacity of the Sichuan Province from 1993 to 2002 have been studied based on the ecological footprint theory and calculation method. The calculation results show that there was an obvious per capita ecological footprint increase and per capita biological capacity（per capita） decrease in the Sichuan Province between 1993 -2002. The ecological footprint surpassed biological capacity, and the development at this rate was unsustainahle. Moreover, it has pointed out the key strategies to maintain sustainable development of the Sichuan Province.
