河南历代大水大旱年表

河南近2000年来旱涝灾害水文气候数据集对探讨历史上特大旱、涝的发生与太阳活动之间的关系，防洪抗旱标准的提出，水资源的合理开发、利用以及进行超长期的水文、气候趋势估报均可提供重要的科学资料。原数据来源于河南省水文总站1982年编制的《河南省历代旱涝等水温气候史料》，《河南省历代大水大旱年表》

The Hydrological and Climatic Dataset of Drought and Flood Disasters in Henan Province over the Past 2000 Years can provide important scientific data for multiple research and application scenarios, including investigating the relationship between the occurrence of historical extreme droughts and floods and solar activity, formulating flood control and drought relief standards, carrying out the rational development and utilization of water resources, and conducting ultra-long-term hydrological and climatic trend forecasting and assessment. The original data is sourced from two works compiled by the Henan Provincial Hydrological Station in 1982: "Historical Hydrological and Climatic Materials of Droughts and Floods in Henan Province Through the Ages" and "Chronology of Severe Floods and Droughts in Henan Province Through the Ages".
