海口生态足迹的动态分析与预测
Natural Science Journal of Hainan University(2011)
Abstract
计算和分析了海口的生态足迹、生态容量、生态盈余及赤字状况,并对2010—2012、2038年的生态足迹情况进行了预测.分析结果显示:2000—2008年,海口生态足迹增长96.72%,年均增长10.75%,生态容量维持在7.4×105~7.9×105 hm2之间;人均生态足迹由0.245 1 hm2增长至0.396 3 hm2,人均生态容量由0.492 3 hm2下降至0.424 8 hm2;生态盈余呈逐年下降趋势,2009年转为生态赤字.可见,海口需要采取有效的措施,以遏制生态足迹过快增长,进一步优化城市发展与生态环境之间的关系.
