摘要
运用生态足迹理论测算了2008—2014年河南省的生态足迹总量与生态承载力,对比分析了生态足迹与生态承载力的关系与内部结构的变动趋势。研究表明:总体而言,河南省的人均生态足迹已超过人均生态承载力,2014年的生态赤字为1.2782hm^2,比2008年增加了0.1135hm^2;人均生态足迹一直是生态承载力的2.7倍之多。从各类生产性土地的生态盈余变动看,耕地和建筑用地有一定的盈余空间,林地在2014年已出现了赤字,草地、水域地和化石能源的生态赤字不断加大,可见河南省的生态环境形势十分严峻。
Based on the ecological footprint theory,this paper estimated the ecological footprint and the ecological capacity of Henan Province from 2008 to 2014,and analyzed the relationship between ecological footprint and ecological capacity and the changing trend of the internal structure. The results showed that: Overall,the per capita ecological footprint of Henan Province exceeded the per capita ecological carrying capacity,the ecological deficit was 1. 2782 in 2014,compared to 2008 increased by 0. 1135 hectares,the per capita ecological footprint was 2. 7 times of the ecological carrying capacity. From the change trend of ecological surplus of every productive land,cultivated land and buildings had some surplus space,woodland had appeared deficit in 2014,the ecological deficit in grassland,water and fossil energy land were increasing. Therefore,the situation of ecological environment of Henan Province was very serious.
