【摘要】 【目的】开发长江流域,推动产业梯度转移,实现可持续发展,形成中国新的经济支撑带,已纳入国家战略。产业承接区是长江经济带可持续发展的关键区域,定量研究该区域生态环境压力,测算可持续发展的阈值,为转变长江经济带发展方式,实现可持续发展提供决策参考。【方法】运用生态足迹模型,动态分析产业承接示范区湖北荆门市2006—2014年可持续发展状况,对产业承接区省域尺度发展现状进行比较研究。【结果】样本期内示范区生态赤字和生态压力先持续增大,协调度逐步变差,2012年达到峰值出现拐点,然后赤字开始减少、压力逐步释放、协调性开始恢复,资源利用率逐步提高,拟合生态足迹与GDP为典型库兹涅茨倒U曲线。承接区与示范区均凸显"高压力、低协调度、低发展水平"特征。【结论】提出落实主体功能区规划、提高产业生态效率和资源配置效率等以较低生态足迹水平越过库兹涅茨倒U曲线拐点的可持续发展建议。更多还原

【Abstract】 【Objective】 It has been brought into the national strategy that we are going to exploit the Yangtze river basin,promote the industrial gradient transfer,and realize sustainable development to form the new economic supporting belt of China. Industrial undertaking zone is the key area to the sustainable development of the Yangtze River economic belt. Studying quantitatively the regional ecological environment pressure and calculating the threshold value of the sustainable development can provide decision-making reference for transforming the development mode of the Yangtze River economic belt and realizing sustainable development.【Method】Analyze dynamically the sustainable development situation from 2006 to 2014 in the demonstration undertaking area of Jingmen using the ecological footprint model,and study comparatively the current development situation of industrial undertaking areas under provincial scale.【Result】During the sample period,the ecological deficit and ecological pressure in the demonstration area continue increasing at first,and the coordination becomes gradually poor. The peak appears in 2012,and then the pressure release. The coordination begins to recover gradually,and resource utilization is becoming efficient. The relation of GDP and ecological footprint fits for typical Kuznets inverted U curve. The undertaking area and demonstration area both highlight the characteristics of "high pressure,low coordination,low development level ".【Conclusion】Put forward the suggestions,which can cross the inflection point of Kuznets inverted U curve with a lower ecological footprint level by carrying out the main function area planning,improving the ecology efficiency of industry and resource allocation efficiency,etc. to realize the sustainable development.更多还原
