湖南省资源型城市可持续发展能力评价——基于生态足迹模型的视角

Evaluation on the Sustainable Development Capacity of Resource-based Cities in Hunan Province Based on Ecological Footprint Model

为对湖南省资源型城市可持续发展能力进行评价,基于生态足迹模型视角,文章对湖南省4个地级资源型城市的生态供需能力进行计算分析,同时引入生态可持续指数分析现阶段可持续程度,并对区域可持续发展能力进行定量评价。研究结果表明:湖南省资源型城市均表现出不同程度的发展不可持续,面临着耕地、草地、水域、建筑用地的生态超载压力,能源资源的生态足迹以原煤的消耗为主导,在很大程度上影响各区域的发展能力。最后根据结论提出应从生态环境、产业结构、消费模式等方面提高资源型城市可持续发展能力。

In order to evaluate the sustainable development capacity of Hunan’s resource-based cities,this paper,based on the ecological footprint model,calculates and analyzes the ecological supply and demand capacity of municipal-leveled resource-based cities in Hunan province.Meanwhile,through introducing ecological sustainability index,analyzes the sustainable development degree in current phase and quantitatively evaluates the regional sustainable development capacity.The study results show that Hunan’s resource-based cities all demonstrate unsustainable development with different degrees,which faces ecological overloading pressures on cultivated land,grassland,water area,and land for building.Besides,the ecological footprint of energy resources has been dominated by the consumption of raw coal,which affects the development capacity of each region to a great extent.Accordingly,it has been proposed that the sustainable development capability of resource-based cities should be improved from the aspects such as ecological environment,industrial structure,and consumption patterns,etc.
