摘要

为探讨水-能源-粮食系统的综合安全问题,从水安全、能源安全、粮食安全、水-能源系统安全、水-能源系统安全、能源-粮食系统安全六个方面选取了26个指标,采用频度分析法构建了水-能源-粮食系统综合安全评价指标体系。然后,完善了物元扩展模型,并将其用于评估京津冀地区水、能源和粮食系统的整体安全性。从时间和空间两个维度考察和研究了用于评估水、能源和粮食系统整体安全的评价指标。实证研究表明,该模型充分体现了水-能源-粮食系统的整体安全性。比较了修正模型和传统物质-元素膨胀模型的评估结果,证实了修正模型的可行性和有效性。最后,利用指数权重和障碍度模型讨论了影响京津冀地区水-能-粮系统安全的主要因素。同时提出了加强水-能源-食品系统安全的相关建议。

To explore the integrated security of water-energy-food system, 26 indicators were selected from six aspects: water security, energy security, food security, water-energy system security, water-energy system security, energy-food system security; the frequency analysis method was used to construct the integrated security evaluation index system for water-energy-food systems. Then, the matter-element expansion model was refined and used to assess the overall security of the water, energy and food system in the Beijing-Tianjin-Hebei region. The evaluation metrics used to assess the overall security of water, energy, and food system were examined and researched from two dimensions: time and space. This model adequately represents the overall security of the water-energy-food system, as demonstrated by empirical studies. Comparisons are made between the evaluation results of the modified model and those of the conventional matter-element inflationary model, confirming the feasibility and validity of the modified model. Finally, the main factors affecting the security of the water-energy-food system in the Beijing-Tianjin-Hebei region are discussed using the index weight and obstacle degree model. Relevant suggestions are also provided to enhance the security of the water-energy-food system.
