| 摘 要： | 从供需平衡状况、供需结构等方面定量分析了重庆市生态系统可持续发展的状况,结果表明:2004年重庆市人均生态赤字1.2806hm2/人,人类活动对区域生态经济系统的影响已超出其生态承载力,区域生态经济系统的结构和功能亟需调整;重庆市人均生态足迹的供需结构具有明显不对称性,可用于人类消费的可供生态空间类型结构较为单一,重庆市生态赤字的存在,进一步揭示了当前人地关系紧张的现状。

| Abstract: | Based on demand and supply balance analysis,an ecological footprint(EF)model of Chongqing City was established.The results show per capita EF deficit to be 1.2806 hm2 in 2004,meaning that eco-economic system demand from human activities exceeds the region's natural system supply limit.The structure and function of the regional eco-economic system needs urgent readjustment as it already proves to be strongly asymmetric.Human consumption exhibits a simplex trend in ecological space.There is an intensification of relationship between the human element and the land element of the ecosystem. |
