Abstract阿富汗是中国提出的"丝绸之路经济带"和"21世纪海上丝绸之路"("一带一路")的重要国家。由于多年的战乱,阿富汗经济发展相对落后,但其拥有较为丰富的矿产资源和独特的区位优势,对中国的经济战略发展具有深远的意义。为了研究阿富汗生态经济系统的可持续发展状况,本文基于能值分析方法,构建了可持续发展评价指标体系,对阿富汗2008-2015年的能值变化进行了定量评估。结果显示,2008-2015年,阿富汗总能值从5.65×10(22) sej增长到9.75×10~(22) sej,但不可更新资源能值占总能值使用量之比一直较低,2008年只有1.72%,这表明阿富汗本地资源没有得到有效的开发利用,经济发展非常依赖于外部资源的输入;可持续发展指数(Emergy Sustainability Index,ESI)从3.00下降至0.72,环境负荷率(Environmental Loading Ratio,ELR)从0.77上升至2.06,能值产出率(Emergy Yield Ratio,EYR)从2.31下降至1.49。以上结果表明,阿富汗资源利用不平衡,经济发展水平较低,可持续发展潜力相对较大,急需开展基础建设和合理的资源开发。
