摘要
通过人工对比观测数据与南宁土壤水分站自动监测数据的对比分析，认为虽然自动监测数据不是很准确，存在一定的系统误差，但除30～40cm土壤层次外．其余土壤层次自动监测数据与人工对比观测数据具有比较一致的变化规律，两者间有较明显的直线正相关，可见自动监测数据经过一元相关方程的订正可趋于准确，可以使用。与此同时给出了各土壤层次自动监测数据的订正模式。
A contrast analysis is employed to investigate the quality of soil moisture from automonitor at Nanning soil moisture station. The results show that there is system error in automonitoring while they have the uniform change regular except at the soil layer in depth of 30～ 40cm. It is indicated that the auto-monitoring data will trend to the accuracy and be initialization through univariate correlation equation. The reduction scheme is also given.
