利用生态足迹分析方法,对浑善达克国家重点生态功能区2012年生态足迹进行了计算,结果表明:研究区人均生态足迹是5.296hm2,人均生态承载力为2.429hm2,生态赤字为2.867hm2,生态形势严峻。按照土地类型统计:1)人均生态足迹中化石能源地的生态足迹最大,其次为草地和耕地;2)人均生态承载力中耕地的人均生态承载力最大,其次是草地和林地;3)人均生态赤字／盈余中草地、化石能源地和水域出现生态赤字,而其他土地类型则出现生态盈余。生态保护与建设的重点是加强草地保护。
The ecological footprint analysis method was used to calculate the ecological footprint of the key ecological function areas in Hunshandake in 2012 and analyze their changes.The results showed that the ecological footprint was 5.296 hm2 per capita,and its ecological carrying capacity was 2.429 hm2 per capita,ecological deficit was 2.867 hm2 per capita,which reveals that this region has made full use of its various land resources.In terms of land use types:(1)Per capita ecological footprint is the largest in natural energy resources land,followed by farmland and forest land;(2)The largest ecological carrying capacity per capita is in its farmland,followed by grassland and forest land;(3)Per capita ecological deficit is found in grassland,energy resources land and waterland,while the ecological surplus appears in the other ecological land types.Key measures of ecological protection and construction in this area are to protect grassland.
