A Comparative Analysis of Soil Moisture between Artificial Observation and Soil Moisture Automatic Station in Sichuan
摘要
Abstract
Six representative stations were selected to analyze the difference and relation between the data from artificial observation and the data from soil moisture automatic station. Through correlation analysis, box-plot analysis, as well as the comparison of their difference, standard deviation and relative error,the large error of all the stations mostly appeared in the subsurface layer was found. Among all of the six stations, the relative error of Pujiang was less than 10% . At present, soil moisture automatic station could only reflect the variation trend of soil moisture. At last, the reasons of the inaccuracy when using soil moisture automatic station data were analyzed. According to this situation, a method for calibrating the automatic monitoring data where the correlation showed well was proposed.关键词
