基于回归分析法的地下水位预测研究

Research on the Predication of Groundwater Level Based on Regression Analysis

彭楼灌区位于山东省聊城市西南部,为引黄灌溉灌区。2002年彭楼灌区复灌以来,有效缓解当地水资源紧缺的矛盾。为研究彭楼灌区引黄水量对地下水位的影响,采用回归分析法,具体分析地下水位变差与引黄水量、干旱指数的回归关系,建立回归方程。通过实例分析检验,建立的回归方程可作为进行彭楼灌区地下水位预测的一种方法。

Locate in southwestern of Liaocheng , Shandong province , Penglou irrigated area is irrigated by the yellow river .The reirrigation of this area since 2002 has alleviate the supply and demand contradiction of water resources effectively .Guided by re-gression analysis method , this paper makes a research on the influence of yellow river irrigation volume on groundwater level of the studied area .To be specific , a regression equation is established according to the regressive relationship between groundwater level variations and the yellow river irrigation amount .Applications of the regression equation on real cases indicate that it is a practical method for groundwater level predication by establishing regression equation .
