| 摘 要： | 针对目前单孔稳定流求参存在的问题，本文在分析新生界松散含水层条件及三次降深抽水过程基础上，利用其抽水试验恢复阶段的数据，分别求得各含水层多个参数，其值真实反映了含水层的实际情况。利用多元回归方法，求得降深与流量关系，通过其系数值大小分析，间接得出各含水层的富水性程度，为地下水的勘探与评价提供一定借鉴。

| Abstract: | As for some questions about obtaining the aquifer parameters using steady flow pumping in single well, three different aquifer parameters, which reflect real values approximately, are obtained through the data of pumping recovery section after analyzing hydrogeological condition of loose aquifers in Cenozoic. By the way of multivariate regression, the relationship between drawdown and discharge is gotten and, according to the values of different coefficients, directly, which provides some the extent of water-bearing of three aquifers is deduced inreference for groundwater exploration. |
