惠北试区降水入渗补给地下水分析

Analysis on Groundwater Recharging by Rainfall Penetration in Huibei Test District

本文用实测统计资料计算分析了惠北试区降水对地下水资源的补给。求出了雨前不同地下水埋深条件下,次降水与地下水位上升的关系式,并提出了能引起地下水位上升的最小次降雨量,对本区30多年降水对地下水资源的补给进行了统计计算,导出了相关性很好的年降水量与入渗补给量的关系式,求出了本区年降水入渗补给系数。

Having analysed the statistical data from a lot of examples grounds-water recharge by rainfall penetration in Huibei' test district has been estimated. Reasonable relationships of ground water accretion to a rainfall under the condition of different depth befor raining was identified minimum rainfall causing rise of ground water was indicated. Coefficient of annual recharge by rainfall penetration was indicated according to more than 30 years statistcal figures in this district.
