| 摘 要： | 以襄阳市为例,运用生态足迹模型,对2009年生态足迹、生态承载力、生态赤字等进行了测算。结果表明,襄阳市2009年人均生态足迹为2.640 839 hm2,人均实际可利用生态承载力为0.444 3 hm2,人均生态赤字达-2.196 540 hm2。说明襄阳市目前己超出了自然生态系统的生态承载力范围,生态足迹与生态承载力之间的矛盾加剧,现有的发展模式是不可持续的,生态环境处于不安全状态。

| Abstract: | With Xiangyang city for example,the ecological footprint model was adopted to predict the ecological footprint,ecological carrying capacity and ecological deficit in 2009.As indicated by the results,the per capita ecological footprint of Xiangyang in 2009 was 2.640 839 hm2 in 2009,and average personal ecological capacity was 0.444 3 hm2,and the ecological deficit rose to-2.196 540 hm2.The research indicated that the utilization of natural resource in Xiangyang had been beyond the carrying capacity of natural ecological system,the conflicts between ecological footprint and ecological capacity aggravated,the present developing model was not sustainable,and the ecological environment was at risk. |
