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.
