基于生态足迹模型的江苏省六大经济区可持续发展评价

运用复种指数调整后的生态足迹模型,利用江苏省的相关统计资料以及GIS技术,对1999-2008年间江苏省六大经济区的生态足迹变化进行了比较分析,并在此基础上进一步对江苏省六大经济区的资源利用效率、生态经济协调性以及社会经济发展趋势予以探讨。研究发现当前江苏省六大经济区处于不同程度的生态赤字状态。基于生态足迹计算结果,进一步引入万元GDP生态足迹、生态经济弹性系数以及可持续发展能力三项指标,从资源利用效率,生态经济协调性以及社会经济综合发展趋势三方面来综合分析评价江苏省六大经济区的可持续发展状况,最终结果显示尽管区域间发展水平有明显差异,但是整个江苏省的可持续发展能力水平在不断提高,总体状况良好。最后根据江苏省六大经济区的可持续发展水平,提出了进一步协调区域间平衡发展的相关建议。

Sustainable development assessment based on ecological footprint model:a case study of six different economic zones in Jiangsu Province

The ecological footprint variations of six different economic zones in Jiangsu Province from 1999 to 2008 were researched by using modified ecological footprint model,relevant statistic data of Jiangsu Province,and GIS technology;besides,the resource utility,eco-economic coordination,and socio-economic progress trend of these economic zones were further investigated in this study.The results show that currently there is ecological deficit of different levels respectively in the six economic zones.Based on the result of ecological footprint calculation,further introducing three indexes including 10000 Yuan ecological footprint,eco-economic elastic coefficient,and sustainable capability,and considering three aspects of resource utilization,eco-economic equilibrium,and overall social economic progress,we comprehensively evaluated the sustainable development of six economic zones.Results indicated that although the development was disparate among the zones,the overall sustainable development capability of Jiangsu Province kept upgraded,revealing a sound developing trend as a whole.Finally,on the basis of the current sustainable development of Jiangsu province,a proposal on coordinating more balanced development among different regions was put forward.
