水文资料在各阶段的使用当中越来越被重视,其合理性和真实性也是越来越严格。本文在分析水文资料实行一算二校、分局审查、省局汇审等环节的可靠性基础上,通过各阶段的错误率建立一灰色预测模型,提出了各阶段可控的错误率白化值及预测值,为科学、客观地评估各阶段水文资料校审质量提供了理论依据。 Hydrological data is more and more emphasized in the use of each stage, its rationality and authenticity are also more and more strict. Based on the analysis of the reliability of hydrological data, such as one count of two schools, the examination of branch offices and the reassessment of provincial bureaux, a gray forecasting model was set up based on the error rate of each stage and the controllable error rate of each stage was proposed. The predicted values ​​provide a theoretical basis for scientifically and objectively assessing the quality of hydrological data at each stage.
