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。 Based on the non-parametric geostatistics idea of ​​extraction Kriging, this paper takes a case study of soil water and salt spatial variability in a typical experimental area in Hetao Irrigation District as an example to test the application of Kriging in soil water and salt evaluation . Comparing with the common Kriging and Kriging estimates, it is found that the Kriging method has the advantage of indicating Kriging, that is, there is no statistical assumption on the data, no special value identification and processing, The accuracy of linear estimation can be used for soil water and salt monitoring and evaluation.
