Abstract
Abstract
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.
