摘　　要：非均质多孔介质的空间分布具有随机性与结构性的双重性质。地统计学方法在研究具有结构性和随机性双重性变量的空间变异性方面具有极强的科学性。本文在地理信息系统平台ArcGIS上,采用Geostatistical Analyst地统计学分析模块中的kriging插值方法研究非均质性多孔介质的空间变异性。以河北省廊坊市地下水污染物的现场数据为研究对象,利用普通克立格法对氟化物、硫酸盐、氯化物和汞浓度的空间变异性进行分析。Spatial distribution of heterogeneous porous media has double characteristics of randomicity and structure. Geostatistic method is scientific in the research of spatial variation of variables, which is both structural and stochastic. In this paper, the spatial variability of heterogeneous porous media was studied based on the Kriging method handled by ArcGIS. The object of this paper is analysis of the data of groundwater contaminants in Langfang, Hebei province, Using Kriging method to analsize the spatial variations of four contaminants.
