| 摘 要： | 在分析应用遥感资料测量土壤水分方法的基础上,运用反演土壤水分的表观热惯量模型,研究了一种可以应用FY-3A数据反演土壤水分的方法。根据一实例,结合实测数据,拟合出表观热惯量与土壤含水量的关系模型,并验证该方法的可行性。结果表明:应用此种方法反演辽西地区春季的土壤水分状况,在0~20 cm土层内具有较高的精度,而在30 cm以下土层的精度较低。据此找到一种适用于FY-3A数据的土壤水分实时监测方法,可为今后运用FY-3A数据反演土壤水分提供一套可用方法。

| Abstract: | Based on the analysis of applying remote sensing methods to measure soil moisture,using apparent thermal inertia model to invert soil moisture,the paper discussed a method of using FY-3A data inverting the soil moisture.Through an example,according the measured data,the relation model of the apparent thermal inertia and soil water content was fitted and the feasibility of this method was validated.Results showed that inverting spring soil moisture status in western area of Liaoning by the method,the accurac... |
