摘要
本文系统论述了土壤空间变异性研究的理论与方法,并首次把这一理论与方法应用于海涂土壤电导率的空间变异性研究。结果表明,海涂土壤电导率的空间变异结构确实是存在的,并表现为线性模型,所研究地块上土壤电导率空间变异结构的变程约为6.0米。这一结果对测定田间土壤的平均电导率具有重要的指导意义。
This paper systematically reports the theory and method of research on soil spatial variability and their first application in the spatial variability study of soil conductivity in the coastal saline soils.Results showed that spatial ,variability did exist in the coastal saline soil,and it fit for a line model.The SVS distance limit of soil conductivity was about 6.0 m in the experiment.This is very helpful in directing the measurement of mean soil conductivity.
