摘要
气象水文数据的可信流通与安全管控对智慧防灾和资源管理意义重大。本文基于区块链的气象水文数据可信流转技术,采用多层架构,遵循可行性、合理性、创新性原则。引入跨链技术以及结合IPFS星际文件系统的混合存储方案,保障原始数据不可篡改性,将高频气象数据检索响应时间压缩至毫秒级。该技术的数据流转处理流程涵盖数据上链与存储、授权与流转、使用与追溯。其关键特性包括去中心化与数据透明性、不可篡改与可追溯性、安全性与隐私保护、高效流转与跨链技术。在实际应用中,有效提升了气象水文数据管理水平,为智慧防灾提供准确及时的数据支持,大幅提升防灾效率,同时为数字孪生流域构建奠定坚实的数据基础。
The trusted circulation and secure management of meteorological and hydrological data are of great significance for smart disaster prevention and resource management.This paper proposes a blockchain-based trusted data circulation technology for meteorological and hydrological data,adopting a multi-layer architecture and adhering to the principles of feasibility,rationality,and innovation.By introducing cross-chain technology and a hybrid storage solution integrating the IPFS(InterPlanetary File System),the immutability of raw data is ensured,and the retrieval response time for high-frequency meteorological data is reduced to the millisecond level.The data circulation process of this technology encompasses data on-chain storage,authorization and circulation,usage,and traceability.Its key features include decentralization and data transparency,immutability and traceability,security and privacy protection,as well as efficient circulation and cross-chain technology.In practical applications,it effectively enhances the management level of meteorological and hydrological data,provides accurate and timely data support for smart disaster prevention,significantly improves disaster prevention efficiency,and lays a solid data foundation for the construction of digital twin watersheds.
