摘　　要：环境足迹表征人类发展过程对环境的影响程度。环境足迹和居民福祉水平是衡量区域可持续发展能力的重要指标。计算了2000-2018年三江源地区的环境足迹与环境边界,构建了三江源地区居民福祉评价框架,评估了2000-2018年三江源地区环境足迹及居民福祉的耦合协调关系及动态变化特征,得到了2000-2018年三江源地区环境足迹与居民福祉间的定量关系,可为有关部门制定合理的区域发展策略提供科学支撑。结果表明:(1)2000-2018年三江源地区人均环境足迹呈一直超过环境边界限额的状态。(2)三江源地区居民福祉按重要性排序表现为社会文化福祉高于安全健康福祉和基本需求福祉。2000-2018年,三江源地区居民福祉总体呈波动式上升趋势,其中安全与健康福祉的波动最大且对居民福祉的贡献度最高。(3)三江源地区环境足迹与居民福祉的耦合度与耦合协调度呈现波动上升趋势,二者关联水平逐渐提高,逐步趋于协调发展。Environmental footprint represents the degree of the impact of human development on the environment.Environmental footprint and human well-being are the important indicators to measure the sustainable development capacity of a region.This paper calculated the environmental footprint and environmental boundary of the Three-River Headwaters region,constructed a framework for evaluating human well-being in the Three-River Headwaters region,and evaluated the coupling coordination relationship and the dynamic characteristics of the environmental footprint and human well-being in the Three-River Headwaters region from 2000 to 2018.The quantitative relationship between the environmental footprint and human well-being in the Three-River Headwaters region was obtained.The results indicated that:(1)overall,the environmental footprint per capita of the Three River Headwaters region from 2000 to 2018 exceeded the environmental boundary limit.(2)Human well-being in the Three River Headwaters region indicated that social and cultural well-being was higher than safety,health,and basic needs in the order of importance.From 2000 to 2018,the overall human well-being in the Three-River Headwaters region showed a fluctuating upward trend,of which safety and health fluctuated the most and contributed the most to the overall human well-being.(3)The coupling degree and coupling coordination degree between the environmental footprint and human well-being in the Three River Headwaters region showed a fluctuating upward trend,and the level of correlation between the two gradually increased,and gradually tended to be coordinated.The results of this study can provide scientific support for the relevant departments to formulate reasonable regional development strategies.
