【摘要】：20世纪90年代以来,生态足迹模型作为定量化可持续评价的重要理论方法得到了广泛的应用。基于传统生态足迹模型,结合遥感产品净初级生产力数据,构建了基于净初级生产力的生态足迹模型,调整了均衡因子和产量因子,并增加了污染物账户。在此基础上,应用传统模型和改进后的模型分别计算了南通市2000~2013年的生态足迹。结果表明:(1)传统生态足迹模型和改进模型下的南通市2000~2013年人均生态足迹都是稳步增长的,改进后的模型变化较小;(2)南通市2000~2013年生态承载力虽有所波动,但整体上呈下降趋势;(3)南通市连续14年出现生态赤字,从2000年的0.308 6 hm~2/人上升到0.587 7 hm~2/人,生态系统处于不安全状态,生态系统的稳定性降低。可见,改进的生态足迹模型能更准确地反映研究区自然资源利用状况。最后,针对南通市生态不安全状况,从土地结构、能源消费等方面提出减少生态足迹的建议。
[Abstract]:Since 1990's, ecological footprint model has been widely used as an important theory and method of quantitative sustainable evaluation. Based on the traditional ecological footprint model and the data of the net primary productivity of remote sensing products, the ecological footprint model based on the net primary productivity is constructed, the equilibrium factor and yield factor are adjusted, and the pollutant account is increased. On this basis, the ecological footprint of Nantong City from 2000 to 2013 was calculated by using the traditional model and the improved model respectively. The results show that both the traditional ecological footprint model and the improved model have a steady increase in the per capita ecological footprint from 2000 to 2013, and the improved model has a small change. The ecological carrying capacity of Nantong City from 2000 to 2013 fluctuates. However, the overall trend is that there is an ecological deficit in Nantong for 14 consecutive years, from 0.308 6 hm~2/ in 2000 to 0.587 7 hm~2/. The ecosystem is in an unsafe state and the stability of the ecosystem is decreased. Therefore, the improved ecological footprint model can more accurately reflect the use of natural resources in the study area. Finally, in view of the situation of ecological insecurity in Nantong City, the paper puts forward some suggestions on reducing ecological footprint from the aspects of land structure and energy consumption.
