不同收入水平的城市居民生活消费生态足迹测算与对比——以河南省开封市为例

本文运用生态足迹的理论和方法,以2009年开封市3个不同收入居民消费水平生活小区为例,采用居民生物资源和能源消费调查问卷数据,定量分析了2009年开封市不同收入水平小区居民的生活消费生态足迹。根据板桥小区、康平小区、龙成花园3 个小区的调查资料,分别计算了3个小区的生物资源消费和能源消费的生态足迹。结果表明:① 从3个小区人均生态足迹来看,总体上能源消耗的生态足迹较大;② 从3个小区居民生物消费的生态足迹来看,猪肉的人均生态足迹最大,奶制品次之,肉类食品和奶制品的生产需要较多的土地面积;③ 通过分析3个小区不同类型的人均生态足迹,板桥小区化石燃料用地和建筑用地所占的比重最大,其次是耕地和草地;收入消费水平越高的居民,生态足迹越大,收入消费水平越低的居民,生态足迹越小。证实了高收入水平居民对生态以及资源的占用程度要远远大于低收入水平居民,造成居民生态占用以及碳排放的不公。最后,提出了有针对性的对策建议。

Estimation and comparison of ecological footprints of urban households' consumption with diffrent income: A case study in Kaifeng City, Henan Province

Taking three residential areas of different income levels in Kaifeng City, Henan Province in 2009 as a case, this study analyzes the ecological footprint of Kaifeng City using the theory and methods of ecological footprint and questionnaire survey. Based on the survey in the three residential areas, Banqiao, Kangping and Longchengxiangxieli Garden, the ecological footprint of consumption of biological resources and energy are calculated. The results indicate that, firstly, in the three residential areas, from the viewpoint of per capita ecological footprint, energy consumption in the overall ecological footprint is at a higher level; secondly, from the viewpoint of biological consumption, per capita ecological footprint of pork is the largest, followed by dairy products, and the reason is that meat and dairy food production requires more land area; thirdly, from the viewpoint of different types of per capita ecological footprints, in Banqiao residential area the percentage of fossil fuel land and building land is the largest, followed by arable land and grassland. Based on the analysis above, we conclude that the higher the residential area's living standard is, the greater the ecological footprint is, and vice versa. This study demonstrates that Kaifeng city's polarization phenomenon is the main reason for the unfairness between the two residential areas in terms of ecological footprints and carbon emissions. Finally, we provide some advices to the urban households and policymakers, such as promoting economic development, actively creating more jobs, and leading the residents to rational consumptions.
