| Abstract: | The scientific basic of application of geo-statistics in the research of soil character was introduced,the ba-sic theories of geo-statistics and perspective of geo-statistics in paddy soil in red soil region were also discussed.Based on the theory of regionalized variables and variograms of geo-statistics,the systematic and complete method on quantitative research on the spatial heterogeneity of soil nutrients in paddy soil in red soil region was established. |
