荒漠化地区生态足迹及相对经济资源承载力分析——以科尔沁左翼后旗为例

Analysis of Ecological Footprint and Relative Carrying Capacity of Economic Resources in Desertified Areas ——A Case in Kerqinzuoyihouqi County

用生态足迹的方法和相对经济资源承载力的研究思路,以科尔沁左翼后旗为例分析了荒漠化地区的生态压力和承载力.结果表明,该旗2000年人均生态足迹需求为2.3064hm2,生态承载力为1.6475hm2,生态赤字为0.6590hm2.并且相对经济资源承载力也较低.在近10a内(和全国平均水平相比)经济资源承载力呈现出减小趋势,即相对贫困状态,这是该区土地荒漠化发生的社会经济根源.

Ecological pressures and carring capacity in desertified areas were studied by use of the method of ecological footprint and the relative carrying capacity of economic resources in Kerqinzuoyihouqi county. The results showed that the ecological footprint per cap and the ecological carrying capacity was respectively 2.306 4 hm^2 and 1.647 5 hm^2, and the ecological deficit was 0.659 0 hm^2 in 2000. Compared with the average level in China, the relative carrying capacity of economic resources was lower in Kerqinzuoyihouqi county, and it had the trend of getting smaller from 1991 to 2000, which was the relatively poor condition, it was the social-economic source of desertification.
