摘要
通过对传统的生态足迹模型进行改进,计算了2014年威县各消费项目的生态足迹、生态承载力.并以生态足迹度作为循环经济发展水平的判定依据,对其进行客观、科学的量化分析.结果表明:首先,威县的人均生态足迹是1.001 5 hm2/人,人均承载力是0.303 1 hm2/人,最终人均生态赤字为0.698 4 hm2/人,赤字的主要原因是耕地、化石燃料地和草地的生态足迹超出了其生态承载力的范围.其次,威县循环经济发展水平的生态足迹度测度结果(EFD)为3.3,表明威县的循环经济处于劣性循环阶段,对于威县发展农牧结合循环经济而言,如何在满足现有水平的消费需求情况下保持生态的可持续发展是当前需要解决的重要问题.
Abstract
On the basis of improving the traditional ecological footprint model,this paper calculated the ecological footprint and ecological carrying capacity of Weixian County in 2014.It made an objective and quantitative analysis of the development level for circular economy by Ecological Footprint Degree(EFD).The result indicated that Weixian County's ecological footprint per capita was 1.001 5 hm2/people,ecological capability per capita was 0.303 1 hm2/people,ecological deficit per capita was 0.698 4 hm2/people.The main reason for the deficit was that the ecological footprint of arable land,fossil fuel and grassland was beyond the scope of its ecological carrying capacity.Secondly,the measurement results of the Ecological Footprint Degree of Weixian County circular economy development level was 3.3.It showed that the Weixian County circular economy was in a inferior circulation stage.How to meet the current level of consumer demand,and maintain the sustainable development of ecology is an important problem to be solved for the development of circular economy in Weixian County.
