摘要
水文预报的目标是对未来的水文现象做出事先估计,它不仅是获取准时预报信息的途径,也是保证工农业安全生产的有效手段。相关回归分析法是数理统计中最常用的一种方法,本文基于此方法对水文资料进行统计分析,结果表明,该方法符合水文现象特性,具有较高的精度,能很好地运用于水文预报工作中。
The goal of hydrological forecasting is to make a prior estimation of future hydrological phenomena.It is not only a way to obtain timely forecast information,but also an effective means to ensure the safe production of industry and agriculture.Correlation regression analysis is the most commonly used method in mathematical statistics.Based on this method,the hydrological data is statistically analyzed.The results show that the method accords with the characteristics of hydrological phenomena,has high precision,and can be applied to hydrological forecasting in the work.
