基于生态足迹的珲春市生态承载力分析

以吉林省珲春市为研究区,运用生态足迹理论对珲春市2006年和2017年的生态足迹、生态承载力及生态压力指数进行了定量计算,并对生物资源消费和能源消费的变化进行了分析.结果显示:珲春市的人均生态足迹呈增加趋势,即由2006年的10.116 hm²/人增加到2017年的11.667 hm²/人; 人均生态承载力呈下降趋势,即由2006年的2.89 hm²/人降到2017年的2.76 hm²/人; 生态压力指数由2006年的1.23降到2017年的0.63,即土地生态安全由较不安全变为较安全.本研究结果可为珲春市的生态发展提供科学依据和决策支持.

Analysis of ecological capacity in Hunchun City based on ecological footprint

Taking Hunchun City of Jilin Province as the research area, the ecological footprint theory was applied to quantitatively calculate the ecological footprint, ecological carrying capacity and ecological stress index of Hunchun City in 2006 and 2017, and the changes of biological resources consumption and energy consumption and related policies were analyzed. The results showed that the per capita ecological footprint of Hunchun increased from 10.116 hm²/person in 2006 to 11.667 hm²/person in 2017. The per capita ecological carrying capacity showed a downward trend with a value decline from 2.89 hm²/person in 2006 to 2.76 hm²/person in 2017. The ecological tension index dropped from 1.23 in 2006 to 0.63 in 2017, indicating that the ecological environment changed safer from less safe. The findings of this study could provide decision support for the ecological development of Hunchun City.
