摘  要:
基于中子法和烘干法测土壤含水率测定数据,采用SPSS软件进行回归分析,分析表明两种方法的结果近似,用中子法测定土壤含水量结果可靠,快速简便;并用回归方程可对缺测土层深度的含水率进行预测。通过对中子法测定数据分析可知中子法测浅层土壤含水率误差略大,并对其误差进行分析提出一些注意事项。

摘  要:
In this paper,both the neutron method and drying method were used to measure the soil water content data,which then was analyzed by using SPSS software.The analysis result showed that the measuring results of the two methods were similar.Using neutron method to measure soil water content can get reliable result and is rapid and simple.Moreover,the soil water content of the un-measuring layer can be predicted by using the regression equation.Through the analysis of the measuring data of neutron method, it could be found that the error of measuring data of shallow layer was slighter larger.In the end,the error was analyzed and some points deserving attention were pointed out.
