陕西省生态承载力供需平衡研究

陕西省经济发展主要依赖矿产资源的开发,尤其是煤炭资源的开发,随着全省经济的快速增长,生态环境问题也逐渐凸显,这一矛盾越来越引起人们的重视.为揭示陕西省生态环境破坏现状及生态环境承载能力,利用生态足迹理论,定量分析了陕西省生态承载能力及可利用空间.经过计算,2014年全省人均生态足迹1.3403 hm2,人均生态承载力1.9286 hm2,可利用人均生态承载力0.3569 hm2.结果表明,陕西省生态承载整体还有盈余,但草地、茶园和化石燃料用地均出现生态赤字,最后分析了产生生态赤字的原因.

Ecological Balance between Supply and Demand in Shanxi Province with Ecological Footprint Method

The economic development of Shan'xi Province is mainly dependent on the development of mineral resources, espe-cially the development of coal resources. With the rapid growth of the province's economy, the ecological and environmental prob-lems are becoming more and more prominent. In order to reveal the status of ecological environment destruction and carrying ca-pacity of ecological environment in Shan'xi Province, the ecological carrying capacity and available space of Shan'xi Province were quantitatively analyzed by using ecological footprint theory. After calculation, in 2014 the province's per capita ecological footprint of 1. 3403hm2 , per capita ecological carrying capacity of 1. 9286hm2 , which can use the per capita ecological carrying capacity of 0. 3569 hm2 . The results show that there is a surplus of ecological carrying capacity in Shan'xi Province, but the grassland, tea garden and fossil fuel land all have ecological deficit. Finally, the causes of ecological deficit are analyzed.
