江苏省城市生态承载力评价

在中国城市化进程不断推进的大背景下,城市健康发展与可持续发展之间的关系日益受到人们的关注。生态承载力评价提供了衡量区域可持续发展潜力的方法。以江苏省为研究对象,选取2007—2016年10年的数据,从江苏省整体(层次1)、苏南苏中苏北三大地域(层次2)及其13个地级市(层次3)这3个层次展开定量分析,评价了江苏省城市生态承载力。生态承载力的评价指标体系包括生态弹性力、资源与环境承载力和社会发展能力3个子系统。结果显示,江苏省城市生态承载力在10年间呈上升趋势,尤其在最近3年的上升幅度较大。

With the constantly advancing of urbanization in China, the relationship between urban healthy development and sustainable development are causing more and more attention. Evaluation of ecological carrying capacity (ECC) provides a method for measuring regional sustainable development potential. Selected Jiangsu Province as a case study to conduct an evaluation of its ECC from 2007 to 2016, conducting a multi-perspective research from three area scales, such as Jiangsu Province as a whole (Level 1), the south, the middle and the north of Jiangsu (Level 2), and thirteen cities in Jiangsu (Level 3). The framework of indicator system contains three sub-systems, namely, ecological resilience, resource and environmental carrying capacity, and social development ability. The results showed that ECC in Jiangsu had an upward trend in the ten years, especially in the past three years.
