湖北省自动土壤水分观测站检定后的数据分析

Analysis of data after verification of automatic soil moisture observation station in Hubei

文章概述了湖北省自动土壤水分站的运行情况,以及完成自动土壤水分监测对农业生产和科学研究的重要意义。通过对湖北省DZN3型自动土壤水分观测传感器检定后数据的比较,分析了人工和自动站观测数据的绝对误差及其相关性,并探讨了导致自动站观测数据误差的主要原因,同时对未通过检验的站点的日常维护提出了建议,介绍的方法为今后开展土壤水分观测传感器检定奠定了基础。

This paper gives an overview of the operation of automatic soil moisture station in Hubei province and the significance of automatic soil moisture monitoring for agricultural production and scientific research.By comparing the data before and after the verification of the DZN3 automatic soil moisture observation sensor in Hubei province,the absolute error and its correlation between the artificial data and automatic station data are analyzed.And the main reasons that cause the data error of the automatic station are discussed.Some suggestions are put forward for the daily maintenance of the stations which have not been tested.The methods introduced laid a solid foundation for the verification of soil moisture monitoring sensor in the future.
