本文采用动态法、区域水量均衡法、数值法确定了通辽地区不同时段的降雨入渗补给系数。在分析不同时段 (月、年 )不同等级降雨量条件下降雨入渗补给系数随地下水埋深的变化关系曲线的基础上 ,找出了α-Δ 线型中不同系数A、B、C随降雨量而变化的回归曲线。从而 ,使我们把规定时段α-Δ - p关系写成一个统一的式子 ,实现了计算机自动化处理 ,并克服了每一区段降雨量均给出不同关系式的缺点
In this paper, dynamic response, regional water balance method and numerical method were used to determine the rainfall infiltration recharge coefficient in different periods of Tongliao area. Based on the analysis of the relationship between the rainfall infiltration recharge coefficient and the groundwater depth under different levels of rainfall over different periods (months and years), the correlation coefficients of different coefficients A, B and C in the α-Δ line with rainfall The amount of change in the regression curve. As a result, we have formulated the α-Δ-p relationship for a given time period as a uniform formula that has enabled computer automation and overcomes the drawbacks of giving different relationships for each section of rainfall
