本文介绍了在江苏省土壤比阻测试的探索中,对土壤比阻k、圆锥指数CI以及土壤物理性粘粒含量A％三个参数的每两两之间的相关问题进行了分析。据江苏土壤比阻测试资料指出,物理性粘粒含量A％与土壤比阻k之间存在良好的相关性,并应用多元回归法获得物理性粘粒含量A％、比阻k和土壤含水量三者间的相关方程、它给预测土壤比阻、绘制比阻区划图提供方便。
This paper introduces the related problems of soil specific resistance test in Jiangsu province, and analyzes the correlation between every two of the three parameters of soil specific resistance k, cone index CI and soil physical clay content A%. According to Jiangsu soil specific resistance test data, physical clay content A% and soil specific resistance k have a good correlation, and the use of multiple regression method to obtain physical clay content A%, specific resistance k and soil moisture content The correlation equation between the three, it is to predict the specific resistance of the soil, rendering specific resistance zone map to provide convenience.
