在山间盆地或山前地带计算地下水补给资源时,往往要计算山区对盆地内部或顿斜平原区的侧向补给量。这部分量在西北干旱地区往往可补给总量的40——50%以上,是一个不可忽视的数量。采用何种数学模型来计算这部分补给量,直接关系到地下水资源评价的质量问题。过去多采用断面法计算,近年来我们发现断面法弊病较多。82年我们在山西忻县盆地进行地下水资源概算中,提出了局部汇水补给量法,效果较好。现将此法的依据和运算过
In the calculation of groundwater recharge resources in mountain basins or piedmont zones, it is often necessary to calculate the amount of lateral replenishment of mountain areas to the interior of the basin or to the plains. This part of the amount in the northwestern arid areas often can supply more than 40 - 50% of the total, is a not negligible amount. The mathematical model used to calculate this part of the supply is directly related to the quality of groundwater resources assessment. In the past, the use of cross-sectional method to calculate, in recent years we found that cross-sectional method more. In 1982, in the calculation of groundwater resources in Xinxian Basin, Shanxi, we proposed a local catchment recharge method with good results. This method is based on and calculated
