摘　　要：运用生态足迹模型及方法,利用武汉市2001—2010年的生物资源及能源消费统计数据,计算武汉市生物资源、能源人均生态足迹,并结合相关指标分析其变化趋势及原因,对未来武汉市可持续发展提出对策建议.研究结果表明:十年来,武汉市人均生物资源生态足迹变化不大,基本稳定在0.75 hm2左右,但人均生态足迹与人均能源生态足迹均呈上升趋势,分别由2001年的1.58 hm2和0.90 hm2上涨至2010年的2.43 hm2和1.65 hm2.能源消耗量的日益增加是导致武汉市人均生态足迹上涨的主要原因.近几年,虽然人均GDP增长和人均能源生态足迹仍然表现出较明显的相关性,但万元GDP生态足迹的下降反映该市能源利用率有所提高,能源消耗增幅低于GDP增幅.The data of consumption in biological and energy resources in Wuhan from 2001 to 2010 are collected and the bidogical resources as well as per capita ecological footprint in Wuhan of each year are calculated by adopting the ecological footprint model and methods. According to related methods,the variation trend by referring to indicators are analyzed,after which,the countermeasures for ecological environment construction in Wuhan city are given. As the results show,during the 10 years,the total ecological footprint and the ecological footprint of energy ascend from 1. 58 hm^2 and 0. 90 hm^2 to 2. 43 hm^2 and 1. 65 hm^2,respectively,while the ecological footprint of biological recourse per capita stays steady at around 0. 75 hm^2. The increasing ecological footprint in Wuhan is mainly caused by the growing energy consumption. The amount of GDP and ecological footprint of energy are obviously correlated; nevertheless,the growth rate of energy consumption is relatively lower than GDP,and the decline in ecological footprint per ten-thousand-yuan GDP reflects the improving utilization of natural resources in Wuhan.
