摘要
近年辽宁省加大了土壤墒情监测设施设备的投入,在西部地区建设固定式土壤墒情自动测报站的基础上又配备了便携式土壤水分自动采集仪。为了提高监测数据准确性,辽阳分局对采集仪进行了参数率定及野外人工土壤墒情对比实验工作。根据实验分析成果,结合多年来人工土壤墒情监测工作经验,了解并掌握了采集仪工作原理及测量精度。
In recent years, Liaoning prov ince has improved the soil moisture monitoring facilities and equipment investment, infrastructure construction of fixed soil moisture automatic monitoring stations in the west of Liaoning and is equipped with a portable soil moisture automatic acquisition instrument. In order to improve the accuracy of monitoring data, Liaoyang branch was calibrated and comparative experiment field artificial soil moisture on acquisition instrument. According to the experiment and the artificial soil moisture monitoring work experience in recent years, we need to know the relationship between the acquisition principle and the manual data collection for more consideration.To understand and master working principles of the instrument and the accuracy of measurements.
