摘要
应用生态足迹理论及模型,根据赣江流域2007年出版的统计数据,对赣江流域2006年的生态足迹和生态承载力进行了定量计算,结果表明:2006年赣江流域的人圴生态足迹为0.9327hm2/cap,而当年实际上可以提供的人均生态承载力为0.9474hm2/cap,人均生态盈余为0.0147hm2/cap,生态需求与生态供给之比为1:1.02,表明人们对赣江流域生态经济系统的影响还未超出其生态承载力的阈值,赣江流域生态系统是安全的,流域发展表现为可持续状态;该流域中赣州、吉安2地市出现生态盈余,分别是0.3488hm2/cap,0.2108hm2/cap;而南昌、九江、宜春3地市出现生态赤字,分别是0.2397hm2/cap,0.1328hm2/cap,0.1696hm2/cap,其中南昌市生态赤字最大。
Based on published statistics data of 2007, ecological footprint and ecological capacity of Ganjiang River basin in 2006 were calculated by using ecological footprint theory and model. Results indicated that average ecological footprint of the basin was 0.9327hm2/cap, while average ecological capacity was 0.9474hm2/cap, per capita ecological remainder was 0.0147hm2/caP and ratio of ecological demand and ecology supply was 1 ： 1.02, which showed the effect on the basin ecoeconomic system does not exceed its threshold of ecological capacity. Eco-system of the basin is safe and sustainable.
