大埋深条件下降雨入渗补给的初步分析

Elementary Analysis of Rainfall Infiltration Replenishment under Great Buried Condition

运用SWAP模型对太行山山前平原——河北省栾城县田间土壤水分运动进行了数值模拟。从土水势及土壤含水量等方面,初步分析了降雨灌溉入渗补给条件下土壤水分运动的规律。通过分析和讨论,探求了大埋深条件下降雨入渗过程,初步揭示了降雨入渗对地下水位变化的影响。

The article is based on SWAP model and did numerical simulation for water movement in the soil of farmland in the piedmont plain of the Taihang Mountains, Luancheng County in Hebei province. From the flow of water, the water-bearing quantity in the soil, and other sides to say, it primarily analyzes regulation of water movement in the soil under the condition of rainfall irrigation and infiltration replenishment. At last, it searches the process of rainfall infiltration under great buried condition and shows influences of groundwater level owing to rainfall infiltration.
