2000-2010年鹤壁市生态足迹动态分析

Dynamic Analysis of Ecological Footprint of Hebi City during 2000- 2010

生态足迹是一种定量测定人类对自然资源利用程度的新方法。为了客观反映鹤壁市市域资源消耗与供给状况,本研究引入生态足迹理论与方法,分析了鹤壁市近10年生态足迹和生态承载力的动态变化。结果表明,2000—2010年期间鹤壁市人均生态足迹呈递增趋势,由2000年的1.373 7 hm2/人增长到2010年的4.342 0hm2/人,年均增幅21.6%。化石能源用地是鹤壁市人均生态足迹增大的主要原因。人均生态承载力总体呈现下降趋势,由0.299 0 hm2/人降至0.280 5 hm2/人,降幅6.2%。人均生态足迹与人均生态承载力之比由2000年的4.59∶1增至2010年的15.48∶1。鹤壁市一直处于生态赤字状态,且呈加剧趋势,其发展处于不可持续状态。

Ecological footprint is a new method to quantify and test the extent of human use of nature resources. In order to reflect the domain of resource consumption and supply conditions, the study introduced the theory and methods of ecological footprint to analyze the dynamics of the ecological footprint and ecological bearing capacity in the latest ten years in Hebi City. The results showed that the per capita ecological footprint had rapidly increased during the period from 2000 to 2010 from l. 3737 hm^2/person to 4. 342 hm^2/person, or 21.6% annually. Fossil energy use was the main reason for the increase of per capita ecological footprint in Hebi City. The per capita ecological bearing capacity presented a descending trend from 0. 2990 hm^2/person in 2000 down to 0.2805 hm^2/person in 2010, or 6. 2%. The ratio of per capita ecological footprint and per capita ecological bearing capacity increased from 4. 59 ： 1 in 2000 to 15.48 ： 1 in 2010, which indicated that Hebi City had have the ecological deficits from 2000 and seen the en larging imbalance trend. Hebi City is in a state of unsustainable development.
