长沙市城市居民生活消费的生态足迹分析

生态足迹是一种定量测量人类对自然利用程度的新方法。以长沙市为例，估算出2003年城市居民的食物、衣着、生活用品、生活用能等主要生活消费的生念足迹为1．0612hm^2。居民生活消费的总生态足迹面积为21619．831km^2，其市区面积为591．33km^2，生活消费的总生态足迹面积是其城市实际面积的36．6倍.最后就建立可持续的居民生活消费方式、促进长沙生态城市建设提出了相应的改善意见．

Ecological Footprint of Living Consumption Per Capita in Changsha

The theory of ecological footprint is used to measure the development level from a new aspect and deal with a certain region's development condition. The ecological footprint of major living consumption per capita in Changsha in 2003 is presented in this paper. The consumption is estimated for each relevant category, which includes food, clothing, household facility, fuel and housing. The results indicate that the ecological footprint per capita is 1.0612 hm2. To accommodate the urban residents,the ecological footprint would be 36 times larger than their territories. At last,to build a sustainable eco-city,we should consider the capacities of ecosystems and advocate the ecological ways of life and consumption.
