摘　　要：运用改进三维生态足迹模型测算了贵州省2010~2019年的生态足迹、足迹深度和足迹广度,通过构建可持续发展综合指数对其可持续发展状况进行了评价。主要结论如下:①人均生态足迹呈“倒U型”变化:2010~2014年人均生态足迹逐年上升,由4.1589 hm^(2)/人增加到4.9048 hm^(2)/人,2016年以后呈现下降趋势。②足迹深度和足迹广度均呈“倒U型”变化,足迹深度2016年达到最大值3.33,2019年降至3.13;足迹广度2013年达到最大值0.9546 hm^(2)/人,2019年降至0.8049 hm^(2)/人;全省存量流量利用比以2016年为节点呈“倒U型”变化。③生态压力指数以2015年为节点呈现“倒U型”变化,10年来都处于极不安全状态;生态多样性指数小幅下降,总体呈现平稳态势;生态资源利用效率指数逐年下降;可持续发展综合指数逐年增加。研究结果表明:贵州省自然资本利用可持续性呈现变好趋势,区域可持续发展能力有所提升。Based on the improved three-dimensional ecological footprint model, the ecological footprint, footprint depth and footprint breadth of Guizhou province from 2010 to 2019 are analyzed. Its sustainable development status by constructing a comprehensive index of sustainable development is evaluated. The main conclusions are as follows:① The per capita ecological footprint showed an "inverted U-shaped" change: from 2010 to 2014, the per capita ecological footprint increased from 4.1589 hm^(2)/person to 4.9048 hm^(2)/person, and showed a downward trend after 2016.② Both footprint depth and footprint breadth showed an "inverted U-shaped" change, with the maximum footprint depth reaching 3.33 in 2016 and decreasing to 3.13 in 2019. The footprint breadth reached the maximum value of 0.9546 hm^(2)/person in 2013 and decreased to 0.8049 hm^(2)/person in 2019. The utilization ratio of stock flow in the province presents an "inverted U shape" with 2016 as the node.③ The ecological stress index showed an "inverted U-shaped" change with 2015 as the node, and remained in an extremely unsafe state for the past 10 years. The ecological diversity index decreased slightly and showed a stable trend on the whole. The utilization efficiency index of ecological resources decreased year by year;The comprehensive index of sustainable development increased year by year. The results show that the sustainability of natural capital utilization in Guizhou province presents a better trend and the regional sustainable development capacity has been improved.
