摘要
通过地下水水位观测资料,将咸阳市(秦都、渭城)按地貌和地质条件分为黄土台原区、渭河北阶地区和渭河南阶地区3个区,利用GIS软件Kriging插值法,并结合地表高程信息对3个分区进行地下水水位插值,探讨咸阳市区地下水位空间规律,并分析Kriging插值误差,讨论基于GIS软件插值效果。
In this paper, based on the observational data of groundwater level, the Xianyang city, including Qindu and Weicheng dis- trict, is divided into three areas according to the topography and geological conditions, namely Loess terrace region, Weihe river North terrace region and Weihe river south terrace region. Combined with surface elevation information, the GIS software and Krig- ing interpolation method are used to calculate the groundwater level in the three districts. Also, the spatial distribution law of groundwater level in Xianyang city is discussed, the Kriging interpolation error is analyzed, and the interpolation effect based on GIS software is discussed.
