摘要
城市化进程飞速,对地下水水位的预测尤为重要。为研究降水量、地表温度以及地下温度对地下水位的影响,采用线性回归分析法建立方程进行预测,并进行改进,引入降水量的平方项。实验表明改进的回归模型能够更为准确的预测地下水位。
With the rapid development of urbanization,the prediction of groundwater level was particularly important.In order to study the influence of the precipitation,the surface temperature and the underground temperature on the groundwater level,the linear regression analysis method was used to establish the equation for prediction,and it was made improvements,the square term of the precipitation was introduced.Experiments showed the improved regression model could predict the groundwater level more accurately.
