【摘要】 针对水文资料整编过程中对于场次洪水的整编效率不高、管理不够标准规范等问题，从需求分析、技术选型、功能实现等方面设计并实现了场次洪水选择系统。提出了数据导入标准规范、数据可视化简洁美观、洪水选择简单直接等系统需求；综合当前主流先进软件开发前端技术，选择了Vue3、ECharts、Element Plus为关键技术，并设计了可执行的技术架构；紧扣系统需求，实现了洪水导入、详情查看、洪水标记、洪水导出等实用功能。系统开发完成后，整体上弥补了水文资料整编过程中缺乏对场次洪水针对性处理的不足，在多个水文站、水库上应用效果良好，对水文资料整编、洪水预报方案编制具有显著的辅助作用。更多还原

【Abstract】 This paper addresses the issues of low efficiency and insufficient standardization in the compilation of flood events during hydrological data processing. It designs and implements a flood event selection system from the perspectives of demand analysis, technology selection, and functional implementation. The paper proposes system requirements such as meeting data import standards, concise and aesthetically pleasing data visualization, and simple and direct flood selection. It synthesizes current mainstream and advanced front-end software development technologies, selecting Vue3, ECharts, and Element Plus as key technologies, and designs an executable technical architecture. Focusing on system requirements, it implements practical functions such as flood import, detail viewing, flood marking, and flood export. After system development, it overall compensates for the lack of targeted processing for flood events in hydrological data compilation. It has achieved good application results at multiple hydrological stations and reservoirs, significantly aiding in hydrological data compilation and flood forecasting scheme development.更多还原
