摘　　要：介绍了土壤性状研究中引入地统计学的科学依据、地统计学的基本原理和地统计学在红壤稻田土壤养分研究上的应用前景。在地统计学的区域化变量理论和变异函数的基础上,建立了一套对红壤稻田土壤养分的空间变异性进行定量化的较系统的研究方法。The scientific basic of application of geo-statistics in the research of soil eharactcr was introduced,the basic 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 uu quantitative research on the spatial heterogeneity of soil nutrients in paddy soil in red soil region was established.
