“八五”期间王家沟小流域生态足迹分析

Analysis on the ecological footprint of Wangjiagou during 1991—1995

以黄土丘陵区王家沟小流域为研究对象,利用生态足迹理论及模型对该流域生态足迹与生态承载力进行了测算。结果表明,"八五"期间王家沟小流域生态足迹由0.536244615 hm2/cap增至0.665469085 hm2/cap,提升幅度为24.10%,生态承载力由0.900738097 hm2/cap增至1.192844588hm2/cap,提升幅度为32.42%,说明水土保持综合治理有效的改善了王家沟小流域生态环境,促进了小流域可持续发展。

Ecological footprint theory and model have been applied to calculate the ecological footprint and ecological capacity, according to the investigation of Wangjiaguu small watershed in the loess hilly and gully region. The results showed that the ecological footprint was gradually increased from 0.536244615 hm2/cap to 0.665469085 hm2/cap, the ecological carrying capacity was increased from 0.900738097 hm2/cap to 1.192844588 hm2/cap, from which a significant improvement of its eco-environment and sustainability was achieved.
