基于生态足迹方法的平江县生态可持续发展能力研究

Research on Ecological Sustainable Development Ability of Pingjiang County Based on Ecological Footprint Method

生态足迹是基于生态生产面积来测度区域可持续发展的生物物理方法,本文运用生态足迹模型对湖南省平江县2009~2014年近6年的生态足迹和生态承载力进行了计算。结果表明：当地人均生态足迹从2009年的1.818221364 hm^2增长至2014年的1.878043008 hm^2,增幅为3.30%。人均生态承载力从2009年的0.603669045 hm^2增加至2014年的0.619426861 hm^2,增幅为2.61%。人均生态赤字从2009年的1.214552319 hm^2增加到了2014年的1.258616147 hm^2,增幅为3.63%。万元GDP生态足迹从2009年的1.956722615 hm^2/万元降低到2014年的1.071649702 hm^2/万元。

Ecological footprint is a biophysical method to evaluate the regional sustainable development based on the ecological productive area. In this paper, the ecological footprint and capacity in Pingjiang Coun- ty of Hunan Province from 2009 to 2014 were calculated using the ecological footprint model. The results showed that the local per capita ecological footprint increased from 1. 818221364 hm^2 in 2009 up to 1. 878043008 hm^2 in 2014, which had an increase amplitude of 3.30%. The per capita ecological capacity increased from 0. 603669045 hm^2 in 2009 up to 0. 619426861 hm^2 in 2014, which had an increase amplitude of 2.61%. The per capita ecological deficit increased from 1. 214552319 hm^2 in 2009 up to 1. 258616147 hm^2 in 2014, which had an increase amplitude of 3.63%. The ecological footprint of ten thousand yuan GDP decreased from 1. 956722615 hm^2 in 2009 down to 1. 071649702 hm^2 in 2014.
