应用协同-泛克立格法估计地下水水位

在许多区域水资源水环境问题中，地下水流和水质的模拟往往采用数值方法，需给出各个节点的初始水位值以反映流场的初始状态.本文阐述了以容易获取的节点地表高程信息，作为协同区域化变量，用协同-泛克立格法进行地下水位估值的原理，并以河南省焦作市修武段地下水数值模拟分析区为例，说明了利用该方法时的实验变差函数获取方法.通过与未加入协同区域化变量地表高程的泛克立格法进行比较，证明本文建议的方法对松散多孔介质区域地下水位估值有更好的效果.

The application of Co-Universal Kriging method for estimation of groundwater table

The principle of Co-Universal Kriging method for groundwater table estimation, proposed by the authors, is presented in this paper. In this method, the elevation of the ground surface at the node of calculation is adopted as another co-regionalized variable. A case study is used to demonstrate the acquistition method of experimental variogram. The comparison of the result derived from Universal Kriging method and that from Co-Universal Kriging method shows that the later can provide with more precise estimation of the water table.
