Other Abstract生态足迹方法是当今很常用的一种量化区域可持续发展程度的模型。本文运用该方法的“综合法”模型,选取1983年、1985年、1988年、1993年、1995年、2000年和2003年共7年的统计资料,从生物资源、住宅、交通、能源几个帐户,对成都市整个市域进行了时间序列分析。计算结果表明,近20a来,成都市一直存在生态赤字,人均生态承载力总体上在下降,而人均生态足迹从1983年的1.20975 hm2上升到2003年的2.86505hm2,人均生态赤字从1983年的0.83238hm2扩大到2003年的2.55899hm2,生态足迹的供需矛盾十分突出。在此期间,单位万GDP的生态足迹和能源消耗量大大减小,说明经济发展对自然资源利用效率明显提高。在研究期,成都生态足迹的多样性变小了,发展能力则增强。成都的人均生态赤字大于全球生态赤字,过多地占用了生态资源,要对生态环境问题承担更多的责任。; The Ecological Footprint method is one of the commonly used models to quantify the degree of regional sustainable development. Applying “synthetic method” of this model, we choose statistic data in year books of seven years, with ledgers of biotic resource, dwelling house, traffic and energy sources, to analyze the whole area of Chengdu in time series. The results show, Chengdu had ecological deficit all along in recent 20 years, and ecological footprint per capita rose from 1.20975 hm2 of 1983 to 2.86505 hm2 of 2003, whereas ecological carrying capacity per capita had declined, so ecological deficit per capita increased from 0.83238 hm2 of 1983 to 2.55899 hm2 of 2003. During the period, ecological footprint and energy consumption per unit GDP(10000) greatly increased, which reflects utilization efficiency of natural resources had improved evidently. Also, diversity of ecological footprint in Chengdu became smaller, but development capacity had been enhanced. Ecological deficit per capita of Chengdu is greater than global ecological deficit, as Chengdu occupies ecological resources excessively, so Chengdu should take on more responsibility for ecological problems.
