摘要
叙述了用最小二乘逼近法和最优化基本原理确定水文地质参数的新方法。在方程式的迭代过程中，水文地质参数的正确性是由水位降深值和试验测量值拟合结果的平均相对误差进行评价的。
According to determination of hydrogeological parameters,with themethods of least square approximation niethod and function extreme value condition,thispaper has been built to calculate the optimal hydrogeological parameters using pumpingtestdata. The equatiOn of determining parameters introduces the basic principle of theoptimization,which is described by a set of linear algebraic equation that is solved bycombination of iterative method.
