摘　　要：针对传统技术面临的数据管理中心化、不公开透明等问题,将区块链技术应用于河长制水质信息管理领域.使用企业级开源框架超级账本技术搭建的河长制水质信息系统将核心水质信息上传至区块链,以实现用户链上信息存证的功能.对于系统中已被非法篡改的水质信息,以验证还原的方式进一步保证数据的安全性和可靠性.实验结果表明:水质信息上链和查询的平均吞吐量达到200 tps以上,最高可达500 tps,符合预期的系统性能要求.In this paper, the blockchain technology is applied to the water quality information management field of the river chief-oriented system, for solving the problems of data management centralization, non-openness, and opaque faced by traditional technologies.The river chief-oriented water quality information system is built with the enterprise-level open-source framework Hyperledger Fabric. It uploads the core water quality information to the blockchain and provides relevant information certification storage function for users.It could restore illegally tampered water information by verification, thus ensuring the security and reliability of system data. Experimental results show that the average throughput of water quality information uploading and query on the chain reaches more than 200 tps,up to 500 tps, which meets the expected requirements of system performance.
