摘要
采用生态足迹模型计算了徐州市2002年的生态足迹和生态承载力,分析了1993￣2002年徐州市生态足迹的动态变化;2002年徐州市生态足迹为1.53hm2/人,生态承载力为0.48hm2/人,生态赤字为1.05hm2/人,生态处于不可持续发展状态;近10年万元GDP生态足迹逐年下降,而总生态足迹和人均生态足迹则呈上升趋势,这说明徐州市总体上经济发展的资源利用方式正在由粗放型转变为集约型,但资源利用效率有待于进一步提高;通过计算与分析指出了徐州城市可持续发展中存在的问题并提出了相应对策。
Took Xuzhou as a case, estimated the EF in 2002 and analyzed the trends of change in the past 10 years;the results show： Xuzhou＇s EF and ecological carrying capacity in 2002 are 1.53hm^2/ pers and 0.48 hm^2/pers respectively, with an ecological deficit of 1.05 hm^2/cap.The ecological deficit reveals that the relationship between human and land is more intense; during1993- 2002, per ten thousand yuan GDP tends to decrease, while the total EF and EF per person tend to increase. This shows that Xuzhou economic development resources usage pattern is transferring from extensive to intensive, but the efficiency of resources usage is still lower. In order to defuse the serious relationship between the human and the ecological environment and to promote the sustainable developing of xuzhou in economics, ecologic and society, some advises are put forward here.
