大湾区农产品冷链追溯系统的构建与实施

摘要

粤港澳大湾区经济持续向好发展阶段，市场对农产品的品质要求逐步提高，安全属性与可追溯特性成为核心需求。保障农产品质量安全、优化物流流转效率，促使冷链追溯系统的搭建成为关键实践路径、依托物联网技术开展全程温控监测，借助区块链技术保障数据真实可查，搭建统一信息交互平台促成跨区域协作衔接，最终构建覆盖农产品生产、加工、运输及销售各环节的全链条追溯机制、该系统的落地应用既能显著减少物流环节中的产品损耗，强化农产品质量安全的保障效能，亦能增强消费者对市场产品的信任度，为区域农业现代化进程推进与供应链高效运转提供有力支撑。

Abstract

As the Guangdong-Hong Kong-Macao Greater Bay Area's economy continues to thrive, market demands for agricultural product quality are steadily increasing, with safety attributes and traceability becoming core requirements. Ensuring product quality and safety while optimizing logistics efficiency has made establishing cold chain traceability systems a critical practice. Leveraging IoT technology for full-process temperature monitoring and blockchain technology to ensure data authenticity and verifiability, along with building a unified information exchange platform to facilitate cross-regional collaboration, ultimately establishes a comprehensive traceability mechanism covering all stages from production to sales. The implementation of this system not only significantly reduces product losses during logistics and strengthens quality assurance but also enhances consumer trust in market products, providing robust support for regional agricultural modernization and efficient supply chain operations.
