| 摘 要： | 在从理论上分析了地表土壤日温差、热惯量和土壤含水量三者的关系后,探讨了由地表土壤日温差推求热惯量、再由热惯量推求土壤含水量的方法,建立了气象卫星热红外遥感监测土壤含水量模型。将所建立的模型应用于实际土壤含水量的监测,做出了辽宁省,1988年8月11日近地表(10cm)土壤含水量分布图,通过实测资料验证,该模型具有较高精度。

| Abstract: | Estimation large area near-surface soil water content has great value.The relations among surface soil diurnal temperature difference,soil thermal intertia and soil water con- tent are theoretically analysed in this paper.The method of calculating soil water content from soil thermal intertia and calculating soil thermal intertia from surface soil diurnal tem- perature difference are researched.The model of soil water content Monitoring by Thermal Infrared Remote Sensing is established.The model has certain precision in accordance with test of the observed data.The proposed model is used to obtain the near-surface soil water content map of Liaoning Province on August 11,1988. |
