中文摘要：

针对常用的利用降水入渗系数法确定的降水入渗补给量不随降水频率等因素而变化的弊端，利用郑州市地下水均衡试验场地中渗透仪长时间观测的系列资料，通过对降水-降水入渗补给量进行系统响应分析，建立了4种岩性、5个水位埋深的年际和月际的降水-降水入渗补给响应函数。研究结果表明，根据当期及前期的年、月降水量数据，利用系统响应分析法建立的降水入渗补给函数能比较准确地计算相应地区的降水入渗补给量。

英文摘要：

The precipitation recharge coefficient used to calculate the precipitation infiltration recharge of groundwater, widely adopted in the groundwater resources evaluation, cannot reflect the change with the frequency and intensity of precipitation. Based on the long term data of the precipitation infiltration recharge measured by the lysimeters and precipitation at groundwater badance test station in Zhengzhou city, annual and monthly precipitation infiltration recharge functions are constructed by systems response analysis according to four kinds of soil and five different depth of groundwater. The results show that the monthly or annual precipitation infiltration recharge of groundwater can be calculated with relative accuracy according to the monthly or annual precipitation data by these functions.
