河北省2006年生态足迹和生态承载力分析

Analysis of ecological footprint and capacity of Hebei Province for the year 2006

  • 摘要: 利用生态足迹模型对河北省2006年的生态足迹、生产足迹、生态承载力进行了计算和比较。结果表明, 2006年河北省人均生态承载力为0.468 3 ghm2, 人均生态足迹为2.189 7 ghm2, 人均生态赤字为1.721 4 ghm2, 人均生产足迹为3.436 3 ghm2, 生态足迹强度指数为4.675 8, 基于消费的河北省生态足迹多样性为0.837 4, 基于生态承载力的河北省生态足迹多样性为0.988 0, 基于生态承载力的河北省社会发展指数为0.462 7, 基于生产消费的河北省社会发展指数为1.833 8, 万元GDP生态足迹为1.290 9 ghm2, 河北省的生态贸易赤字为-1.246 6 ghm2, 生态耗竭值为2.794 3 ghm2。表明河北省生态经济系统处于生态耗竭、不可持续状态, 生态多样性低, 生态经济发展能力较差, 经济发展属于高能源消费型。河北省只有改革产业结构, 转变经济发展方式, 建立节能降耗机制, 才能实现可持续发展及对自然资源的合理利用。

     

    Abstract: By using ecological footprint model and data on Hebei Province for 2006, the ecological footprint, production and ecological capacity of the province were calculated. From the study, per-capita ecological capacity, ecological footprint, production footprint, ecological deficit and ecological footprint intensity of the province are estimated to be 0.468 3 ghm2, 2.189 7 ghm2, 3.436 3 ghm2, 1.721 4 ghm2, 4.675 8 respectively. Ecological footprint diversity indexes on the basis of ecological footprint and ecological capacity for Hebei Province are respectively 0.837 4 and 0.988 0. Also social development indexes based on ecological footprint and ecological capacity for the study area are 1.833 8 and 0.462 7 respectively. Ecological footprint for 104 yuan GDP is 1.290 9 ghm2. Ecological trade deficit and ecological overshot in the region are respectively -1.246 6 ghm2 and 2.794 3 ghm2. The findings suggest that the ecological and socio-economic systems of Hebei Province are under ecological overshot and deficit, meaning that current development strategies in the province are unsustainable. Inner industrial structures must be adjusted and new energy consumption mechanisms developed for the realization of ecological sustainability and healthy economy.
