摘 要:本文引入生态效率概念,基于能值生态足迹法,评价我国资源型城市的生态效率,兼与宜居城市进行比较分析,以探讨资源型城市可持续发展状况。研究发现,与宜居城市相比,资源型城市生态效率低下;资源类型和城市规模对生态效率影响较大,二产比重、单位GDP能耗与生态效率负相关;城市人均绿地面积、建成区绿化覆盖率则正相关。因此,延长产业链,提高资源使用效率,发展循环经济,缓解生态压力,对于提高生态效率,至关重要。In order to make the conditions of sustainable development in resource - based cities, a concept of eco - efficiency was introduced in this paper and a comparative analysis is made to the livable cities based on the measure of energy ecological foot- print. Compared with the livable city, the ecological inefficiency of the resource - based cities is lower. With the analysis of fac- tors, it showed that the type and scale of the city had significant impacts and the secondary industry accounted for the proportion of GDP, energy consumption per unit of GDP had negative correlation with eco - efficiency, whereas urban per capita green area, built -up area green coverage rate had positive correlations. Therefore, extending the industrial chain, increasing the efficiency of the use of resources, developing circular economy, and easing ecological pressure are important to improve eco - efficiency.
