摘要
对于许多区域水资源问题 ,用数值方法进行地下水水流模拟时 ,需要给出每个节点上地下水位值。本文着重阐述了地质统计学的基本原理和克立格方法及其在地下水位估值中的应用 。
In many cases of regional water resources issues, when numerical method is often adopted in groundwater flow modeling,groundwater level on each node should be given.The principle of geostatistical approach and Kriging method and its basic application in estimating groundwater level is expounded in this paper.It is indicated that when doing groundwater level estimation universal Kriging method is spatial optimal estimation one.
