| 摘 要： | 对于许多区域水资源或水环境问题，地下水水流模拟往往要采用数值方法，需给出每个节点上初始水位值，以反映流场的初始状态。另外，地下水水位动态长期监测分析，需由观测点水位估计任一点的水位。文中阐述了地下水水位估值的地质统计学方法－泛克立格法原理，以河南省焦作市修武段地下水数值模拟分析区为例，分析了用一次、二次漂移的泛克立格方法模拟地下水初始流场的估值情况和对真实流场特征的反映情况。指出在进行区域地下水位

| Abstract: | In
many cases of regional water resources and water environment issues,numerical method is
often adopted in groundwater flow modeling and initial flow regime value on each node should
be given in order to reflect the initial flow regime.Besides,groundwater level at any point should
be estimated in the analysis of groundwater monitoring.The principle of geostatistical approach
universal kriging method adopted in groundwater level estimation is presented in this paper
and a case study of initial groundwater flow simulation for numerical modeling of groundwater
flow in Xiuwe County,Jiaozuo City,Henan Province is given.In the case study,the result of
simulation of initial groundwater flow regime based on linear drift and quadratic drift universal
kriging method is analyzed and the extent to reflect the actual initial flow regime characteristic
is shown.It is indicated that when doing regional groundwater level estimation good effect can
be obtained by universal kriging method with linear drift. |
