摘要
在介绍生态足迹的概念和计算方法及目前的研究成果的基础上,分析生态足迹模型存在的缺陷和不足,提出了生态足迹改进模型,对成都市2003年至2007年的生态足迹进行了计算,并对成都市的可持续发展状况进行分析。结果表明:成都市人均生态足迹从2003年的1.1221hm2增长到2007年的1.1914hm2,人均生态承载力从2003年的0.2902hm2减少到2007年的0.2580hm2。根据在改进模型下的指标计算结果,近5年来成都市经济有了一定发展,但仍处于相对落后的阶段,而且生态压力大,生态与经济的协调性差,生态建设和经济发展的任务还很艰巨。
On the basis of introduction to the conception, calculation and development, some faults of ecological footprint were analyzed. Improved models were introduced and then applied for calculation of ecological footprint in Chengdu City from 2003 to 2007. The result showed that the per capita ecological footprint increased from 1. 1221 to 1. 1914 hm2, and the per capita ecological carrying capacity decreased from 0. 2902 to 0. 2580 hm2. According to the new model calculation, the economy of Chengdu City had developed a lot in recent five years, but still in the stage of underdevelopment. Actually, the ecological pressure was severe and the mutual compatibility between ecology and economy was poor. Chengdu City still faces challenges in ecological construction and economic development.
