水文信息化在鄱阳湖超历史大洪水中的应用

Application of hydrological informatization in super-historical flood in Poyang Lake

2020年,鄱阳湖流域发生超历史大洪水,湖区堤防险情多发频发,3座万亩以上圩堤相继发生溃决。以防御鄱阳湖流域超历史大洪水为例,在分析江西水文信息化现状和发展规划的基础上,分别对智能感知监测系统、水文业务支撑系统、大数据分析技术,以及可视化会商系统在超历史大洪水的应急监测,预警预报,调度及水情服务等工作中取得的实际应用效果进行分析。结果表明,江西水文构建的水文信息化建设体系,在覆盖范围、自动化水平、工作效率效果、及时准确程度、预警预报分析手段等方面均取得较好成效,有效提升水文支撑保障能力,也为今后进一步强化信息化技术与水文业务深度融合,促使水文在防灾减灾方面提供更加全面、可靠、智能的服务夯实基础。

In 2020,a super-historical flood occurred in the Poyang Lake Basin,dike danger frequently occurred in the lake area,and three dikes over 10000 mu broke out one after another.Taking super-historical flood prevention in the Poyang Lake Basin in 2020 as an example,this paper respectively analyzes practical application effects of intelligent sensing monitoring system,hydrological business support system,big data analysis technology and visual consultation system in emergency monitoring,early warning and forecasting,dispatching analysis and hydro-regime services of super-historical floods.Results show that the hydrological informatization construction system,constructs by Jiangxi Hydrology,achieves good results in terms of coverage,automation level,work efficiency,timeliness and accuracy,early warning and forecasting analysis means,improves the capacity of hydrological support effectively.Also,the hydrological informatization construction system lays a solid foundation for further strengthening the deep integration of information technology and hydrology business in the future,and facilitating hydrology to provide more comprehensive,reliable and intelligent services in disaster prevention and alleviation.
