摘　　要：以实测土壤含水率资料为基础 ,通过假设检验方法系统地分析了田间土壤含水率的统计特性 .分析结果表明 ,田间土壤含水率为近似符合正态分布的随机变量 。Based on measured data, the statistical characteristics of soil water content are studied. Statistical tests show that the soil water content is a random variable, which approximately obeys the normal distribution. The conclusion provides a theoretical basis for the analysis and control of error in soil water content monitoring.
