摘　　要：本文采用不同的实验方法及数学处理方法给出了通辽地区不同非饱和带分区上的次降雨入渗补给系数 ,文中首次将“野外三水转化法”用于降雨入渗系数的推求上 ,当然 ,也不排除一切行之有效的传统实验及数学分析方法。文中通过对不同方法计算成果的对比分析表明 :对于平原区 ,当地下水位埋深较浅 ,且在地下水未开采时段内 ,用“地下水动态资料分析法”推求降雨入渗系数仍然是很准确的 ,鉴于该法所用资料易于获得 ,且在区域上分布均匀 。The coefficients of rainfall infiltration in different unsaturated zones are worked out using different experiment methods and mathematical methods, which is include the coefficients of rainfall infiltration in different times and periods. It is first time to use the`converting method of three waters in field' in the calculation of the coefficients of rainfall infiltration, however, the traditional experiment and the mathematical analysis are also used. It is shown that ,through the analysis and comparison of the different calculation results, the results of rainfall infiltration coefficient calculated with the `analysis of groundwater regime' is very correct in the low depth lf groundwater table of plain and during the non-pumping period. Since the data is easy to get by this method and the distribution is even in the area,the results calculated by this method will be used chiefly.
