太原市2003年生态足迹的计算与分析

The Calculation and Analysis of Ecological Footprints of Taiyuan in 2003

文章计算和分析了太原市2003年生态足迹:2003年该市生态足迹为5.621 hm2/人,可利用生态承载力为0.264 hm2/人,出现了5.357 hm2/人的生态赤字,生态足迹是生态承载力的21.3倍,总的生态赤字相当于自身面积的26倍;并把太原市城市生态系统的受压力程度和资源利用效率与已有的研究结果做了比较,表明该市资源利用效率较低,城市生态系统所受压力偏大;最后提出缓解城市生态压力的若干建议。

Sustainable development has gained much concern with society and academic domains, therefore it also an important issue that needs to be studied further; The ecological footprint method put forward in the late 1990s and improved by William Rees and Mathis Wackernagel presents a methodologically simple but integrated framework for national natural capital accounting, which is capable of measuring the impact of human＇s consumption on ecosystem. In this paper, we calculate and analyses the ecological footprint of Taiyuan in 2003. The result shows that the ecological footprint of Taiyuan is 5.621 hm^2 per capital, the available ecological capacity of Shanxi province is 0. 264 hm^2 per capital, the ecological deficit of Taiyuan is 5. 357hm^2 per capital in 2003. The ecological deficit shows that human load has already stayed beyond the regional ecological capacity greatly, and the regional natural ecosystem is under great pressure of human activities, to which human should pay sufficient attention. Then comparing Taiyuan＇s urban ecosystem stress degree and resource utilization efficiency with some existing achievement of other cities, it can indicate that the resource utilization efficiency in Taiyuan is relatively low , the pressure that its urban ecosystem receives is abnormally great. At last, some suggestions to alleviate this city＇s ecological pressure are also offered.
