摘要
本文将平原地区浅层地下水(潜水)区分为“浅埋”和“深埋”两种类型。对地下水位浅埋时的土壤水分动态过程进行了描述。对地下水位深埋条件下的非饱和土壤水分动态进行了分析,将其划分为四个特征带;并就地下水位连续下降时的土壤疏干补给问题进行了初步探讨。本文所述问题对平原地区四水转化关系研究具有积极意义。
This paper describes the soil water movement characteristics in the case of shallow or deep groundwater table.The characteristics of soil water movement in respose to shallow ground water are shown in four different stages,and the unsaturated soil profile in respose deep ground water can be divided four different section.Finally,the withdrawal discharge and specific yield due to continuous drawdown of ground water table have been discussed.
