摘要
生态足迹是一种定量测量人类对自然资源利用程度的新方法。在阐述生态足迹概念及模型的基础上,运用生态足迹分析法,对河南省(1990-2003年)的消费状况进行了分析与计算。结果表明:河南省的人均生态足迹年均增长率为4.33%,而人均生态承载力仅为0.73%;人均生态足迹的供需比例由1:2,65增至1:3,93,供需矛盾进一步加大。1990年河南省的人均生态赤字为0.688hm^2,到2003年生态赤字已高达1.277hm^2,年均增长率为4.2%。随着人口增长及其相应消费水平的上升,河南省生态系统处于过度利用和压力之下,正在远离可持续发展方向。
Ecological footprint is a kind of quantitatively measuring the extent of humanity's use of nature. A comprehensive introduction to the concept of ecological footprint and computer model was given. The authors calculated and analyzed the ecological footprints of Henan Province in 1990-2003. The result indicates that the per capital ecological footprint had increased with a rate of 4.37% per year, while the ecological capacity only 0.77%. At the same time, the ratio of demand and supply is increased from 2.65 : 1 to 3.93 : 1, and the imbalance trend is enlarging. The ecological deficit is 0. 688 hm2 per capital in 1990, and mount continually with the high speed of 4.2% per year. Above all, it reflects that the regional ecosystem is under great pressure of human activities with the population increasing and the level of life improving. The regional economic development of Henan Province is far from sustainable development.
