摘　　要：合理站网布置是实现对地下水超采区水位动态准确观测的一个重要条件。本文利用克里金法对已有超采区的观测数据进行插值分析,从而确定了满足精度要求的观测站布置密度。计算结果表明,随着站点密度的增加,插值误差减小,在达到一定密度后误差减小速度变缓,趋向于0。Reasonable layout of the monitoring network is an important precondition to realize the accurate dynamic observation of the groundwater level in overdraft area. Based on Kriging method, the observed data from an overdraft area is analyzed with inter- polation method, and then the layout density of the monitoring network that accords with the requirement of the accuracy is deter- mined. The calculation result shows that the interpolation error is reduced with the increase of the density of the network and the reducing speed of it tends to zero after reaching a certain density.
