摘要: 伴随着传感器技术的发展,市场上出现了多种类型的土壤水分传感器,其中,基于介电法原理的传感器技术,如时域反射法、时域传输法、频域分解法及驻波比法应用最为广泛。通过对土壤水分传感器性能、结构、测量尺度、安装和应用中的问题及解决方法进行探究,总结目前传感器技术在土壤水分监测中的应用。结果表明:当前土壤水分传感器在性能、结构上存在差异性,在测量尺度上存在不确定性,安装方法上可分为垂直剖面法、阶梯法和单点法,在实际应用中,深层土壤水分及小尺度土壤水分自动监测技术以及传感器统一标定方法有待进一步研究。

Abstract: As the development of sensor technology, soil moisture sensors are prevalent in current days. The most popular type of soil moisture sensors are based on dielectrometry including time domain reflectometry (TDR), time domain transmission (TDT), frequency domain decomposition (FD) and standing-wave ratio (SWR), which were analyzed through performance evaluation, structure breakdown, measurement standard, installation, application and troubleshooting in this paper. The results showed that different sensors presented different performance and structures, the measurement scale was uncertainty, and the installation methods included vertical profile method, ladder profile method and single point method. In the practical application, the automatic monitoring of deep and small scale soil water and the unify calibration method of sensor needed further study.
