土壤墒情监测中的潮汐现象探析

潮汐现象是沿海地区的一种常见的自然现象,受太阳和月亮等天体引潮力的作用,地球的岩石圈,水圈和大气圈都会产生周期性变化。作为覆盖在地球陆地表面的土壤,在引潮力作用下,不同土层含水量也会发生周期性变化,这种周期性变化在干旱地区往往难以观测,在土壤相对湿润的环境条件下,使用高灵敏度的土壤墒情监测设备可以捕捉到该现象。阐述潮汐现象的相关理论,建立土壤墒情潮汐模型,分析土壤墒情潮汐现象,利用频域反射原理传感器对土壤墒情进行多年监测实验,从大量的采集数据分析,发现疑似土壤墒情潮汐现象,为避免该现象对土壤墒情监测的影响提供一定的理论依据。文中试验结果并不深入,方法、仪器、地点、环境都可能对试验结果有影响,仅供参考。

Exploration and analysis of tidal phenomena in soil moisture monitoring

The tide phenomenon is a common natural phenomenon in the coastal area, the sun and the moon and other celestial tidal force, the earth''s lithosphere, hydrosphere and atmosphere will produce periodic change, as in the coverage of the earth''s land surface soil, the tidal force under different soil moisture will occur periodically, the periodic change is often difficult to observation in arid regions, in relatively moist soil conditions, soil moisture monitoring equipment with high sensitivity can capture the phenomenon. This paper expounds the related theory of tide phenomenon, a soil moisture tidal model, analyzed the soil moisture tide phenomenon, the soil moisture sensor on the frequency domain reflection principle for monitoring experiment, analysis from the collection of large amounts of data, found a suspected soil moisture tide phenomenon, provide a theoretical basis in order to avoid the effect of the phenomenon of soil moisture monitoring. The test results are not in depth, methods, equipment, location, the environment may have an impact on the results of the test, for your reference.
