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估值时线性漂移的泛克立格法即可取得很好的效果。
For many regional water resources or water environment problems, groundwater flow simulations often involve numerical methods. The initial water level at each node is given to reflect the initial state of the flow field. In addition, the dynamic long-term monitoring and analysis of groundwater level needs to estimate the water level at any point from the observation point water level. In this paper, the geostatistics method of groundwater level estimation - Universal Kriging principle is introduced. Taking the groundwater numerical simulation analysis area of Xiuwu section in Jiaozuo City of Henan Province as an example, Method to simulate the initial value of groundwater flow field valuation and the real flow field characteristics of the situation. It is pointed out that the results of the universal Kriging method with linear drift in the estimation of regional groundwater table can achieve good results.
