摘 要: 地下水动态受一系列自然和人为因素的影响,其变化是一个十分复杂的非线性过程;LM(levenberg-marquardt)算法具有逼近最小误差的速度快、精度高等特点,利用其进行地下水位预测研究,结果表明:速度快,误差小,具有推广价值。 Due to influence of natural and artificial factors, the change of groundwater regime takes a complicated nonlinear course. LM (levenberg-marquardt) arithmetic is characterized by approaching the minimum error rapidly with high precision. The application of LM arithmetic in groundwater level forecasting study had demonstrated its speed and less error, so as to prove that it deserves to be spreaded.
