铁岭市生态足迹时间序列分析

运用生态足迹理论,分析了1995~2004年铁岭市生态足迹和生态承载力.分析表明近十年铁岭市平均生态足迹2.07 hm2/cap,平均生态承载力1.22 hm2/cap,平均赤字0.851 hm2/cap,生态处于不可持续发展状态.在铁岭市生态足迹构成中,能源足迹比例最大,十年来能源足迹占总足迹的比例一直在60%左右,2003年高达63%,最低的年份是1999年,为59%;耕地足迹次于能源足迹,大约在26%~31%之间;接下来依次是建筑用地、牧草地、水域和林地足迹.通过对铁岭市生态足迹强度和生态效率情况的分析,对铁岭市可持续发展提出了对策和建议.

Time Series Analysis of Ecological Footprint in Tieling City

Analyzes theoretically the ecological footprint and ecological capacity of Tieling City from 1995 to 2004. The result shows that in this time period the average ecological footprint, capacity and deficit were 2.07, 1.22 and 0.851 hm^2/cap, respectively, i.e., the city is in a state of unsustainable development. In the total ecological footprint the largest proportion resulting from energy consumption is about 6096, up to 63% in 2003 down to 59% in 1999. The second largest one is cropland, about 26% -31% and, sequentially, the land for building, grazing land, aquatic area and forest land. Taking account of the footprint intensity and ecological efficiency of the city, an ecological strategy is proposed for its sustainable development with some advice given.
