Research Advance on the Theories and Methods of Motor-pumped Wells Layout in Irrigation Districts

近些年,我国灌区普遍存在着地下水开采过量、机井布局不合理等问题,从而造成地下水位严重下降、土壤荒漠化加剧、植被枯死等现象。因此,做好灌区机井的合理布局成为控制地下水位下降、改善区域生态环境的重要手段。在总结现阶段机井布局理论和方法的基础上,分析了其中的不足,并对未来的发展进行了展望。

In recent years, the over-exploitation of groundwater and the unreasonable layout of motor-pumped wells have been generally existed in the irrigation districts of China, which lead to the serious drop of groundwater level, soil desertification and the death of vegetation. Therefore, the optimization layout of wells becomes a crucial method to control the groundwater level and improve the regional ecological environment. In this paper, the theories and methods of the layout of motor-pumped wells are presented. The existent deficiencies and the development of the wells planning are discussed.
