摘　　要：在简要介绍生态足迹及相关概念和计算方法的基础上,以大庆市2004年统计年鉴为依据,计算出大庆市2003年的生态足迹为2.6657hm2、生态承载力为0.90313hm2、生态赤字为1.7626hm2。经分析认为生态赤字主要是由于石油生产和加工所致,人类的生产强度超过了生态系统的承载力,大庆生态系统处于人类过度开发利用的压力之下。After introducing the concept of ecological footprint and it＇s calculation method, the ecological footprints of Daqing city in 2003 according to the data of the statistical yearbook were calculated and analyzed.
