摘要
生态足迹是衡量一个地区生态可持续发展程度的重要指标之一。本文应用生态足迹模型对青海省1985—2009年的生态足迹进行了测算,结果表明:青海省人均生态足迹从1985年的1.2287 hm2/人增加到2009年的2.7850 hm2/人,青海省生态足迹的增加主要是由于能源资源消费量的增加;万元GDP/生态足迹大幅提高,生态足迹/万元GDP大幅降低,表明青海省资源利用率和生态效率有一定的提高。
The ecological footprint is an important indicator measurement of ecological sustainable development degree.In this paper,using the ecological footprint model calculated the Qinghai ecological footprint from 1985-2009.The results showed that： from1985-2009,per capita ecological footprint of Qinghai Province increased from 1.2287 hm2 / person to 2.7850 hm2 / person.The increasing of Qinghai Ecological Footprint was mainly due to increased consumption of energy resources,substantially increased of ten thousand Yuan GDP / ecological footprint,and significantly reduced the ecological footprint / million GDP.It is indicating that the resource utilization and eco-efficiency in Qinghai Province has improved to some extent.
