摘要: 生态足迹模型已广泛应用于可持续发展和生态承载力评估中。本文以大连市统计资料为依据,计算了大连市的人均生态足迹和人均生态承载力,用来分析大连市生态可持续发展情况;同时基于生态足迹理论,运用水足迹模型,计算了大连市2001年的水足迹。结果表明:从1991—2004年,大连市人均生态足迹整体呈上升趋势,多年人均生态足迹均在2.250 hm2·人-1以上;2004年为3.965 hm2·人-1,是1991年(2.250 hm2·人-1)的1.76倍,2000—2004年大连市存在不同程度的生态赤字现象;2001年人均水足迹为748.270 m3·人-1,低于北方人均水足迹水平,属于水资源短缺型城市。

Abstract: Ecological footprint (EF) model has been widely used in evaluating sustainable development and ecological capacity (EC). Based on the statistics of Dalian City, its EF per capita and EC per capita were calculated to evaluate the ecological sustainable development of the city. In the meantime, the water footprint of the city in 2001 was analyzed by using water footprint approach. The results showed that from 1991 to 2004, the ecological footprint per capita of Dalian had an overall increase, with the mean EF being 2.250 hm2 per capita or more. The EF was 2.250 hm2 per capita in 1991 and 3.965 hm2 per capita in 2004, and there existed different level ecological deficit from 2000 to 2004. The water footprint in 2001 was 748.270 m3 per capita, being lower than the mean level of North China, suggesting that Dalian City belonged to water deficit area.
