中文摘要：

本文基于非参数地质统计学的析取克立格法思想，以河套灌区内一典型实验区的土壤水盐空间变异性为案例，进行了析取克立格在土壤水盐评价的应用试验研究。经与普通克立格、指示克立格估计值对比分析发现：析取克立格法具有指示克立格的优点，即对数据无统计假定，不涉及特异值识别与处理，又可提高非线性估值的精度，可用于土壤水盐监测与评价工作。

英文摘要：

Based on the spatial variation of soil water - salt at one representative experimental section in Hetao irrigation zone, direct- ed by Distinctive Kriging of non - parameter Geostatistic theory, this paper researched the DK applying in the soil water - salt estima- tion. Compared with the Ordinary Kriging and Indicator Kriging estimating values, it is founded that DK has the characteristics of indi- cator kriging, no need to statistical assumptions for raw data, not involving identification and specificity values treatment, improving ac- curacy of nonlinear estimation, so it can be used to monitor soil water salt and evaluation work.
