摘要
采用正则化最小二乘方法研究了含水层参数识别问题．通过合理选取正则化参数能够解决参数识别中的不稳定问题．同时通过合理布置水头观测点的位置和补充流量条件解决了参数识别中的唯一性问题．数值计算结果表明，在水头观测误差为1cm～2cm的条件下，参数识别结果的误差不超过1％．
The aquifer parameter identification has been studied with normalized least square method. The unsteady problem was overcome through reasonably selecting normalized Parameters in the parameter identification. The nonuniqueness of the inverse solution has been solved by means of reasonably selecting measurement points and adding flow quality condition. The numerical computation results show that the error of parameter identification is not greater than 1% under the measurement error 1 cm～2 cm.
