摘要 本文以成都市1999年和2003年统计年鉴和龙泉驿区统计年鉴1998年和2003年的数据为依据,采用生态足迹的方法,对龙泉驿区1998年和2003年的可持续发展性进行定量评价,通过计算和分析,结果表明龙泉驿区1998年和2003年人均生态足迹均为赤字,且2003年比1998年的生态足迹赤字更为加剧,这反映出人类的生产、生活强度超过了生态系统的承载能力,此区域生态系统处于过度开发利用和压力之下,随着经济的发展,人口的增加,这种趋势还在继续加大。 According to the data of the statistical yearbooks of Chengdu 1999 and 2003 and Longquanyi District 1998 and 2003, the author calculates and analyzes the Ecological Footprint of Longquanyi District in the two years, which reflects that the human load has already exceeded the regional bio-capacity. The result indicates that the regional natural ecosystem is under great pressure of human activities, and with the development of population and economy, the deficit tends to increase.
