采用数值方法，模拟分析了6种典型土壤的1m主体在不同蒸发强度条件下地表下20，50，100cm处土壤水分通量与地下水理深之间的关系。研究结果表明：若以5d或10d为平均时段，在一定的地下水理深条件下，土壤剖面中各深度的水分通量与土壤质地及水面蒸发强度间的关系可用土壤水分包络线图来表示。应用该包络线图，可分析计算裸地不同地下水埋深、不同蒸发条件下地下水对1m主体的补给量。在同样的水面蒸发强度下，地下水埋深起大，则谷深度的水分通量越小，当地下水理深大于3m时，地下水对1m主体已基本没有补给。
The relationship between soil water flux at 20, 50, 100 cm below the subsurface and groundwater depth was simulated and analyzed by numerical method using 1m main body of six typical soils. The results showed that the relationship between water flux and soil texture and water surface evaporation intensity under different groundwater depth can be expressed as soil moisture envelopment diagram when averaged for 5 days or 10 days . The envelope map can be used to analyze and calculate the recharge of groundwater with different groundwater depths under different evaporation conditions to 1m main body. Under the same water surface evaporation intensity, the groundwater depth increases, and the water flux at the valley depth is smaller. When the local water depth is more than 3m, the groundwater basically has no supply to 1m main body.
