基于生态足迹理论的江苏省可持续发展研究

[目的]基于生态足迹模型定量分析江苏省的可持续发展情况。[方法]根据2006—2015年江苏省相关统计数据,研究江苏省的生态足迹总量动态变化、不同生态、生产性土地生态足迹、人均生态足迹、生态承载力及生态赤字。[结果]2006—2015年江苏省总生态足迹以年均3 547.882万hm~2/a的速度增长,人均生态足迹从2006年的5.90 hm~2上涨为2015年的9.67 hm~2。不同类型土地生态足迹贡献率从大到小依次为建设用地、化石能源用地、耕地、林地、草地、水域。江苏省处于生态盈余状态,但自2012年下降明显。[结论]整体看来,江苏省处于可持续发展状态。

Study on the Sustainable Development of Jiangsu Province Based on Ecological Footprint Model

[Objective]To evaluate the sustainable development situation in Jiangsu Province based on ecological footprint model. [Method] According to related data in Jiangsu Province during 2006-2015,total dynamic change of ecological footprint, ecological footprint of different ecological productive land, per capita ecological footprint, ecological carrying capacity and ecological deficit of Jiangsu Province were studied. [Result] The results showed that during 2006 - 2015, the total ecological footprint of Jiangsu Province increased by the rate of 35. 47882 million hm2 per year,per capita ecological footprint increased from 5. 90 hm2 in 2006 to 9. 67 hm2 in 2015. The decreasing order of regarding the rate of contribution for ecological footprint from big to small was constructive land, fossil energy land, cultivated land, forest land, grassland, water area. Jiangsu Province was in the state of ecological surplus, which has declined obviously since 2012. [Conclusion] In general,Jiangsu Province is in sustainable development state.
