摘　　要：采用D、18O同位素峰值位移法求出研究区大气降水入渗补给量。通过野外地中渗透计法和降水入渗系数法对同位素法计算结果检验,发现D、18O同位素法计算结果具有较高精度,同时验证了在研究区用D、18O同位素方法求大气降水入渗补给量是可行和可靠的。用该方法求解大气降水入渗补给量具有方便快捷、经济省时的优点,在湿润、半湿润地区大气降水补给研究方面,具有很大的应用潜力和重要的应用价值。The D, ^18O isotopes peak displacement method is used to estimate the precipitation infiltration quantity in the study area. By comparing the result of the field lysimeter method and precipitation infiltration coefficient method, the isotopes method is a good method and its results are accurate. The isotope results give a proof that the application of D,^18O isotopes peak displacement method on calculation of the precipitation infiltration are accurate and reliable. The method is convenient, efficient, and economic for researching on the precipitation infiltration recharge. It has a considerably application potentiality and important use in the research of precipitation infiltration recharge in humid and semi-humid areas.
