The spread of the global COVID-19 epidemic, home quarantine, and blockade of infected areas are essential measures to prevent the spread of the epidemic, but efforts to prevent and control the outbreak lead to the disruption of fresh and cold chain agricultural products in the region. Based on the multi-layer management model of non-scale agricultural households in China, we applied the complex network theory to construct an evolutionary model of the Chinese fresh cold chain network with adaptation degree priority connection, dual local world considering transport distance connection relationship, and superiority and inferiority mechanism. Based on this model, we studied the evolution of fresh cold chain disruption, and puts forward the optimal design of fresh cold chain network disruption and reconnection from the perspective of practicality and economy.
全球 COVID-19 疫情的蔓延，居家隔离，疫区封锁是防止疫情扩散的必要措施，但疫情防控工作的开展导致疫区的鲜活冷链农产品遭到破坏。基于中国非规模农户的多层级管理模式，我们应用复杂网络理论构建了一个具有适应度优先连接、考虑运输距离连接关系的双层局部世界以及优势劣势机制的中国鲜活冷链网络演化模型。基于此模型，我们研究了鲜活冷链破坏的演化，并从实用性和经济性的角度出发，提出了鲜活冷链网络破坏与再连接的优化设计。
