| 摘 要： | 为了自动土壤水分观测资料更准确、更好地服务于实际应用以及应用于科学研究，从理论上分析自动土壤水分观测与人工实测值存在误差的原因及修正办法，通过公式 ，用每次计算的土壤容重的平均值代表修正的土壤容重，分析评估用修正的土壤容重计算土壤重量含水率的可行性。结果表明：土壤容重修正公式可靠，利用自动观测土壤水分含水量以及土壤容重修正公式来计算土壤重量含水率可行，理论上可以取消逢八观测，也为自动土壤水分观测资料的实际应用、为两年一度的自动传感器评估提供一种指导方法。

| Abstract: | In order to automatic soil moisture observation data more accurate, better services for the practical application and the application in scientific research, based on the theoretical analysis of automatic soil moisture observation and manual measured value of the error and the correction methods, through the formula , the average value of soil bulk density and soil bulk density on behalf of correction for each calculation, analysis and evaluation of the feasibility of calculating soil gravimetric moisture content in the soil bulk density correction. The results show that: the soil bulk density correction formula is reliable, the use of automatic measurements of soil moisture content and soil bulk density correction formula to calculate the soil moisture is feasible, theory can cancel every eight observation, also provides a guide for practical application, automatic soil moisture observation data for automatic sensor biennial assessment. |
