摘要
循环经济是区域实现可持续发展的重要模式,生态效率方法是研究循环经济的比较合适的定量方法。经济、资源和环境协调发展是当前研究的重要课题,利用生态效率分析模型,以徐州市为案例,对徐州市2000年-2007年的生态效率及演变趋势进行了评价。结果发现,徐州市2000年-2007年间,资源效率与环境效率都有提高,生态效率也增长了1.12倍。徐州市循环经济处于比较有活力的发展空间,但是随着社会经济发展的资源环境约束性增强,提高生态效率成为促进徐州市循环经济建设的关键。
Circular economy is an important model for the region to realize the transition of sustainable development, and the method of eco - efficiency is appropriate to analyze circular economy. The coordinated development of economy, resources and environment is an important subject of current research. This article takes Xuzhou City as the example of ease, the eco - efficiency and evolution trends of Xuzhou City from 2000 to 2007 are evaluated by the use of eco - efficiency analysis model. The results showed that,the resource efficiency and environmental efficiency of Xuzhou City from 2000 to 2007 has improved and eco- effciency also increased by 1.12 times. The circular economy system in Xuzhou City is in more energetic developing situation and restriction of resource and environment has increased with the socio - economic development. So the key to promote the construction of circular economy is the improvement of the eco - efficiency of Xuzhou City.
