摘  要:
地统计学应用于土壤科学中,探索其空间分布特征及其变异规律,已为越来越多的学者所推崇。半方差函数提供了一个定量工具,可以将土壤某一性质的变异与成土因子和成土过程联系起来,使人们加深对土壤的作用后果的理解,而克立格可以对未采样区的区域化变量的取值进行无偏最优估计。在对地统计学的理论进行简要阐述的基础上,介绍了其近几年的发展,回顾了它在土壤科学研究中取得的一些成果,并就地统计学在土壤科学中的应用前景作了展望。

摘  要:
The geostatistics is used in soil science to explore its spatial distribution characteristics and its variability law, it has been advocated by more and more experts. Semivariogram as an quantified tool can combine the variance of soil attribute with the form of soil to make the researchers understand deely soil process. Kriging is optimal predictor for regionalized variable at unsampled region. In this paper, the basic theories and recent developing tendency of geostatistics was introduced,finally the perspective of geostatistics in soil science was also discussed.
