生态足迹从生物生产力的角度量化人类消费活动对生态环境的综合影响，是目前国际上应用最广泛、最受关注的可持续发展评价方法，具有简明易懂、可操作性强、易于与其他指标结合等优点，但由于其对人类消费活动的过度依赖，在回顾和总结国内外该领域研究的主要成果和进展的基础上，针对生态足迹理论在能源消费评价中存在的不足，从以下几个方面进行了系统的分析和总结：一是当量因子、产量因子和能量因子等参数的选择都处于两难境地;生态足迹与生态承载力的度量标准存在矛盾：生物生产性土地利用类型相互排斥的假设与客观事实不符;四是对问题的研究不够全面;最后，评价结果存在一定的不准确性，存在相对性、局限性和生态偏差等缺陷，其中前三项应尽快修正，后两项是今后需要逐步克服的，并对生态足迹理论的完善提出了一些有针对性的措施和改进建议。为完善区域可持续发展评价的系统工程，应通过跨学科合作，将更多的经济社会指标引入生态足迹的进一步研究。
Ecological footprint,which quantifies the comprehensive impact of human consumption activities on eco-environment from a standpoint of biological productivity,is the most widely used and concerned method of sustainable development assessment in the world by now.Ecological footprint is excellent in conciseness,understandability,maneuverability and easily being combined with other indicators,but still couldn't reflect the impact of human consumption activity on eco-environment factually and exactly because of its hyper-pessimistic evaluation results.Based on the review and summary of the main achievements and progress in this research field home and abroad,the shortcomings of ecological footprint theory in energy consumption assessment are analyzed and concluded systematically to solve this problem in the following aspects: Firstly,the parameters,including equivalence factor,yield factor and energy factor,all are in a dilemma;Secondly,the measure standards between ecological footprint and ecological carrying capacity are in contradiction;Thirdly,the assumption that biologically productive land use types are mutually exclusive goes against the objective fact;Fourthly,the studies on the issues are not comprehensive;Lastly,the evaluation results are partly incorrect with the defects of relativity,limitation and ecological deviation.Among these five shortcomings mentioned above,the former three items should be modified as soon as possible,while the latter two items need to be gradually overcome in the future.And there are some pertinent measures and improvement suggestions put forward and discussed to improve ecological footprint theory.Moreover,in order to perfect the systemic project of regional sustainable development assessment,more economic-social indicators should be introduced into the further research on ecological footprint through interdisciplinary collaboration.
