| 摘 要： | 岩溶塌陷地层的样本数据中常含有大量的客观存在的特异值,普通克里格法对此类数据的处理存在自身难以克服的缺陷.本文首先介绍了指示克里格的基本原理,运用空间数据分析技术对样本数据的空间分布和空间结构等性质进行分析,确定了最佳模型和相关参数,最后以徐州市塌陷区为例,在GIS平台上构建了基于指示克里格法的复杂岩溶地面塌陷区特征提...

| Abstract: | Plenty of outliers objectively exist in sampling of Complex Karst Strata,which are handled by ordinary Kriging with drawbacks hard to overcome.In this paper,indicator Kriging theory was described.It used the indicator variogram as a main tool to analyze the structural characteristics of the spatial distribution of the Xuzhou Karst Strata,and the results indicated that the distribution of the ground elevation in this area exists clear anisotropy;by applying the indicator Kriging,the paper constructed a spati... |
