摘 要:通过对2000—2014年盐源县生态足迹的计算,评价盐源县生态现状及生态可持续状况。结果表明,2010年盐源县生态足迹最高,达4.418 0 hm^2/人。生态赤字也在2010年达到最高,为3.349 0 hm^2/人,在2010年后生态赤字状况有所改善。2000—2014年生态承载力呈下降趋势,在2014年达到最低,仅1.040 3 hm^2/人。从盐源县生态足迹结构分析可知,盐源县耕地所占的生态足迹过大,超过其他5种土地类型的生态足迹总和。盐源县的生态赤字状况在2010年后呈下降趋势,可见盐源县的生态状况向乐观方向发展。Based on ecological footprint calculation of Yanyuan County from 2000 to 2014, the ecological status and ecological sustainability conditions in Yanyuan County were analyzed and evaluated. According to the results, it showed that the highest ecological footprint in Yanyuan County reached 4.418 0 hm2/people, the highest ecological deficit reached 3. 349 0 hm2/people in 2010. The situation of ecological deficit in Yanyuan conditions has improved in 2010. However, the capacity of ecological carrying in Yanyuan County was not optimistic, which had a downward trend form 2000 to 2014. And it reached a minimum value of 1. 040 3 hm /people in 2014. In addition, through the analysis of the structure of ecological footprint in Yanyuan County, it revealed that the cultivated land in Yanyuan County had larger fraction of ecological foot-print ,which was greater than the sum of the other five land types. Fortunately, the ecological deficit in Yanyuan County had a downward trend after 2010. Therefore, the ecological status in Yanyuan County were optimistic.
