摘要
本文利用强大的数据计算分析软件MATLAB对土壤水分空间变异进行分析,并通过对样地数据插值和趋势面分析,方便地得出了样地土壤水分的变化趋势,计算分析结果对水土保持和农田灌溉都有很好的指导作用。
This paper tries to analyze the spatial variability of soil water with MATLAB, which is a software with a great function in data operation and processing. By data interpolation and trend surface analysis of sampling plots, the trend of variability of soil water is attained. The result has a certain guidance to soil and water conservation and farmland irrigation.
