摘　　要：基于Thies公式和最小二乘原理,采用Lingo软件对非稳定流抽水试验资料进行水文地质参数估值,计算结果表明:Lingo计算值与实测降深值之间非常接近,二者相关系数达到了0.996,且占总数83.33%的数据点其相对计算值和实测值之间的相对误差小于5%,完全满足工程应用要求。Lingo具有的编程简单、运行速度快和计算结果准确等优点,使其在水文地质研究领域得到广泛应用。Hydrogeological parameters were estimated by Lingo in the paper, basing on the unsteady flow pumping test, Thies and Least Square theory. The results by Lingo indicates that they＇re very close to the observed drawdown value, with a correlation coefficient of 0.996, and 83.33 percentage of them have a relative error no more than 5%, which completely meets the requirement of engineering. It will widely used in the hydro - geological studied field because Lingo has characters of simples,speediness and precision.
