用不同土质的标准土壤样本对土壤水分传感器归一化频率进行第一次订正拟合，进而对比自动、人工土壤水分观测数据进行第二次拟合，分析对比差值、相关系数等，结果表明，二次订正拟合方法能进一步提高自动土壤湿度数据的准确性，其相关性与数据拟合方法和数据选取有关，在拟合时应选取合理的数据。采用二次订正拟合方法对29个观测站的土壤水分监测资料分析发现，拟合后的土壤湿度与实际土壤墒情相关性提高。

T his study successively got through w ith correction and fitting of the soil m oisture sensor by using norm alized frequency point at differenttypes ofsoiltexture,and then the second fitting by com parison betw een the autom atic and m anualsoilm oisture observation data and analysis of the difference and correlation coefficient. T he results show ed that this m ethod could im prove the accuracy of autom atic soil m oisture data,the correlation depended on data fitting m ethod and data correctselection,and this m ethod enhanced the correlation betw een fitted soilm oisture and the actualsoilm oisture from the relatde data findings in 29 stations.
