基于生态足迹理论的宜居城市建设研究——以安徽省临泉县为例

运用生态足迹模型,以安徽省临泉县为例,测算了其生物资源、能源消费及建设用地的生态足迹。结果表明,临泉县生态足迹存在生物生产性土地面积供需总量失衡、矛盾突出、受"域间贸易"影响致生态足迹与生态承载力构成不对称等问题;与安徽省生态足迹平均水平进行对比分析,发现临泉县暂时属于弱不可持续发展等级,相当于安徽省1994年的状态;结合临泉县城市产业经济特点,基于生态足迹角度的分析,认为人口因素、产业结构和经济发展方式是临泉县面临的生态压力的主要根源。基于测算结果,提出了临泉县建设宜居城市的建议。

Study on the livable city construction from the perspective of ecological footprint theories: a case study of Linquan County of Anhui Province

By the eco-footprint model,this article takes Linquan County for example to measure the eco-footprint of biological resources,energy consumption and construction land.The results show that the eco-footprint in Linquan County is of imbalance between demand and supply,and that the eco-footprint in Linquan County is greatly influenced by the factor of "regional trading" which leads to dislocation between the eco-footprint and the ecological carrying capacity in Linquan.A further comparison is made with the average level of the eco-footprint in Anhui province.It is concluded that Linquan stays at an unsustainable level,equal to the level of Anhui Province in 1994.Based on the analysis to the footprint level,it points out that population factors,industry structure and economic development path are three main factors which affect Linquan’s footprint level.In the end,it puts forward some suggestions based on the measurement to the livable city construction of Linquan County.
