摘要
土壤墒情监测迟迟不能实现自动化,主要原因是墒情监测仪器的监测精度始终停留在只能定性地监视旱情的变化趋势,无法用自动监测数据准确分析出不同的干旱等级和计算出对应的受旱耕地面积。结合吉林省墒情监测工作实际,开展了土壤墒情监测仪器拟合公式的研究,提出了土壤墒情监测仪器拟合公式的最佳形式,对于仪器厂家转变观念,改变仪器公式形式,提高仪器监测精度,早日实现墒情监测自动化具有很好地参考价值。
The automation is not realized for the soil moisture monitoring. The main reason is that the soil moisture monitoring instruments with their accuracy can only qualitatively determine the trend of drought change, and can not analyze the different grades of drought and calculate the drought farmland area based on the automatic monitored data. This paper made a study on soil moisture monitoring instrument fitting formula, gave the best form of soil moisture monitoring instrument fitting formula.
