摘要
在利用相关分析预报地下水动态变化的过程中,由于忽视了回归方程中相关系数稳定性问题,经常会得到不理想的预报结果。本文在系统地介绍相关系数稳定性检验方法的基础上,通过对甘肃省武威盆地地下水动态变化的预报检验,提出了解决这一问题的办法,即分段截取法。该法使采用相关分析对地下水动态变化做出较高水平的预报成为可能,该法既简单又实用。
In the forecast course of the groundwater dynamical changes using the correlation analysis method, a result of inaccurate forecasts might be often got because of the neglect of the correlation coefficient stability of the regression equation. On the basis of systematical introduction about the inspection method of interrelation coefficient stability, this paper has proposed a solution to this problem-that is, segmentation and/or interception method, through the forecast inspection of the groundwater dynamical changes in the Wuwei Basin,Gansu Province.Thus,it is possible to make the higher level forecast of the groundwater dynamical changes by correlation analysis method. This method is easy and practical.
