南京市生态足迹时空特征及脱钩效应分析

【摘要】：为探寻资源环境与经济增长的可持续发展道路,利用修正的生态足迹模型,回顾了2000~2014年南京市生态足迹、生态承载力及生态赤字的时空特征,依据《南京市国民经济和社会发展十三五规划纲要》趋势外推生态足迹变化情况及其与经济增长的脱钩状态。结果表明:2000~2014年南京市人均生态足迹和人均生态赤字快速增长,人均生态承载力缓慢下降;研究期内南京市各区都出现了不同程度的生态赤字,且生态承载力呈现中心城区低,近郊和远郊区高的格局;生态足迹与GDP之间呈现弱脱钩、强脱钩、扩张连接3种状态,且弱脱钩指数不断减小,经济增长方式开始由粗放型向集约型转变;若按当前资源环境损耗量发展,"十三五"期间生态足迹继续增加,未来在实现可持续的经济增长方式上仍需努力。因此,南京市应坚持调整产业结构,转变经济增长方式;严格执行生态保护红线、永久基本农田保护红线,城市开发边界等"三条红线";实行差别化的国土空间格局优化措施;控制人口过快增长;逐步构建基于生态资产流转的生态补偿机制。
[Abstract]:In order to explore the sustainable development path of resources, environment and economic growth, using the modified ecological footprint model, this paper reviews the spatial and temporal characteristics of ecological footprint, ecological carrying capacity and ecological deficit in Nanjing from 2000 to 2014. According to the outline of the 13th Five-Year Plan for the National economy and Social Development of Nanjing, the change of ecological footprint and its decoupling from economic growth were extrapolated. The results showed that the per capita ecological footprint and per capita ecological deficit increased rapidly and the per capita ecological carrying capacity decreased slowly in Nanjing from 2000 to 2014. There are three states of weak decoupling, strong decoupling and expansion connection between ecological footprint and GDP, and the index of weak decoupling is decreasing, and the economic growth mode is beginning to change from extensive to intensive. The ecological footprint will continue to increase during the 13th Five-Year Plan period, and the sustainable economic growth pattern will still need to be achieved in the future. Therefore, Nanjing should persist in adjusting the industrial structure, changing the mode of economic growth, strictly implementing the "three red lines", such as ecological protection red line, permanent basic farmland protection red line, urban development boundary, etc. To control the rapid growth of population and build ecological compensation mechanism based on the circulation of ecological assets step by step.
