摘  要:
运用流域概念把江西省划分为(环)鄱阳湖区、抚河、信江、赣江、修河及饶河流域和其他外河流域7大部分。运用生态足迹模型计算了前6大部分在2000~2006年间的生态供需状况,并在时间和空间上对它们进行了比较分析。结果表明:①所有研究区域均存在生态赤字,且赤字在不断增大,区域处于不可持续发展状态;②耕地足迹需求均占总足迹需求的80%左右,科学保护和开发耕地资源具有重要意义;③草地和林地资源具有不容忽视的生态赤字。

摘  要:
The Jiangxi Province was divided into seven parts by the concept of watershed,namely Poyang lake area,Fuhe,Xinjiang,Ganjiang,Xiuhe,Raohe and the other river watersheds.The ecological supply and demand status of the former six parts from 2000 to 2006 every two years was computed based on the ecological footprint model and a spatiotemporal comparative analysis to them was conducted.The result showed that:①all the study areas had an increasing ecological deficit and they were in the status of unsustainable development;②their arable land footprints' demand were about 80% of their total footprints' demand respectively,so it was of great significance to protect and exploit arable land resources scientifically;③the ecological deficit of grassland and forest resources can not be ignored.
