| 摘 要： | 本文用实测资料统计计算分析了惠北试区降雨对浅层地下水资源的补给。用非线性回归问题的迭代法，求出了雨前不同埋深条件下，次降雨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(也称临界雨量)，用本区41年的降雨资料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雨量与年入渗补给量的关系式，求出了多年降雨入渗补给系数。

| Abstract: | According to the statistics of actual survey data and calculation, the article analyzes the rainfall to feed shallow groundwater resources in Huibei test area. With the iterative method of nonlinear regression issue, it educes the relation formula between a rainfall and groundwater level ascending under the conditions of different groundwater depths, and puts forward the minimum rainfall (also called critical precipitation) that can cause groundwater level ascending. On the basis of statistic rainfall data in recent 41 years in this area, calculated the replenishment of groundwater resources and got a good relation formula between yearly rainfall and yearly infiltration replenishment and obtained the coefficient of rainfall infiltration replenishment for mutiple years. |
