摘　　要：应用生态足迹理论及模型,根据嘉陵江流域2002年的统计数据,对嘉陵江流域2001年的生态足迹和生态承载力进行了定量计算.计算结果表明:嘉陵江流域2001年总生态足迹高达64 654 135hm2,人均生态足迹为1.439 5hm2,高于全国平均水平;流域人均生态承载力为0.619 8hm2,仅相当于人均生态足迹的43.06%,人均生态赤字0.819 7hm2.嘉陵江流域属于全球尺度可持续而地方尺度不可持续的发展类型,应从减少人均生态足迹、提高土地产出率和控制人口三方面入手,减小生态赤字,促进区域可持续发展.Based on the statistic data of 2001, this paper has applied ecological footprint theory and model to calculate the ecological footprint and ecological capacity of Jialingjiang River Basin. The total ecological footprint is 64654135hm^2, the average value is 1.4395 hm^2, higher than the nation＇s. ＂The average ecological capacity is 0.6198 hm^2 , just equal to 43.06% of ecological footprint. The percapita deficit is 0.8197 hm^2. This result shows that the development type of Jialingjiang River Basin is not sustainable in area scale, but sustainable in golobal scale. Some countermeasures should be taken to deduce ecological decifit and promote sustainable development of this basin. These countermeasures include deducing percapita ecological footprint, improving productive capacity of land and controlling population.
