Analysis of Ecological Carrying Capacity of National Key Ecological Function Areas in Hunshandake Based on Ecological Footprints

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 hm2per capita,and its ecological carrying capacity was 2. 429 hm2per capita,ecological deficit was 2. 867 hm2per 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.
