【Abstract】 The relationship between geostatistics and sampling site design and outlier processing was introduced.The characteristics of geostatistical analytical tools such as the spatial auto-correlation analysis and semi-variogram were discussed.The development situations of the related researches at home and abroad were reviewed.Starting from the scale effect of spatial soil heterogeneity,the application advantages of geostatistics methods in the studies of the scale effect was evaluated.Finally,the ecological significance of spatial soil heterogeneity and the exploration role of geostatistics for the soil ecology and patterns were discuused.The latest development trend and existing problems of geostatistics were discussed.更多还原
