Abstract:

This paper applies the ecological footprint method to study the ecological footprint of lands, steels, cements, woods, and building wastes during construction projects, calculates the ecological footprint value from a statistical method. Based on a case study of a construction project in Xi'an city, the per capital ecological footprint is 4.57 times of Xi'an's ecological loading capacity in 2004, meaning a deficit. This paper presents some suggestions decreasing the ecological deficit in construction projects and reducing the energy consumption, which ensures a sustainable development of ecological footprint.

Key words: construction projects, ecological footprint, ecological loading capacity, sustainable development

摘要：

基于生态足迹分析法，对工程建设项目的土地、钢材、水泥和木材以及工程项目建设过程中产生的建筑垃圾进行生态足迹分析，统计汇总得出工程建设项目生态足迹，并以西安市某一工程建设项目为例，开展实证研究。结果表明：该工程建设项目人均生态足迹约为西安市2004年人均生态承载力的457倍，属于生态赤字状态。在此基础上，提出减小工程建设项目生态赤字、降低工程建设项目能耗，从而实现可持续发展的建议。
