摘要
根据生态足迹的基本思想,结合能值分析理论,建立酸沉降污染的生态足迹计算模型,将酸沉降对自然资源造成的损失和对环境容量的占用转化为生物生产性土地面积,以直观反映SO2和酸雨对地区生态环境的污染和破坏作用,并将建立的模型应用于福建省2006年酸沉降污染生态足迹的实证研究。结果表明:2006年福建省酸沉降的生态足迹为8.67×106hm2,占全省总足迹的4.24%,将其生态占用增加到传统生态足迹账户中,能有效改进传统生态足迹模型中忽略环境污染和生态破坏影响的不足,提出的酸沉降污染生态足迹模型的建立方法对其他同类污染物生态占用的估算具有借鉴意义。
According to integrated the basic theory of ecological footprint with emerge analysis, the loss of natural resources and environmental capacity, caused by acid deposition, was transformed to bio - productive land area, so the ecological footprint model of acid deposition pollution was built up in this paper. Moreover, the established model was applied to the practice study of acid deposition pollution of Fujian Province in 2006. The results showed that the acid deposition ecological footprint was 8.67× 10^6hm^2, which occupied 4. 24% of the total one of Fujian in 2006. Added it to the ecological footprint account, can effectively complemented the calculation of area environment pollution and ecological damage to traditional ecological footprint model. The a- boved model established method can also provide a useful reference of assessing the ecological footprint of other similar pollutants.
