结合现有的城市防洪汛情预警等级判定方法,利用多元线性回归预测模型,提出了一种能够考虑多种影响因子共同作用下的城市防洪汛情预警等级判定模型,该模型对各相关因子的相关性比较高。利用济南市典型降雨数据对该模型进行了检验,结果表明:该模型回归效果良好,可以用于济南城市防洪汛情预警等级的判定。
Combining with the existing urban flood control flood forecasting grade judgment method and using the multiple linear regression prediction model, a predictive model of urban flood control flood forecasting grade under a combination of various influence factors is proposed. The correlation coefficient between the model and the relevant factors Higher. The model was tested by using typical rainfall data in Jinan City. The results show that the regression model of the model is effective and can be used to determine the grade of urban flood prevention and flood warning in Jinan.
