中文摘要：

以河套灌区解放闸灌域为研究区域，以LandsatETM＋影像为数据源，采用土壤水分光谱法并借助回归分析建立农田土壤水分遥感反演模型并进行模型检验。结果表明，模型精度达到81％以上。可为河套灌区农田大范围的土壤水分实时、快速监测提供方法依据。

英文摘要：

Jiefangzha Irrigation Sub district of Hetao Irrigation was selected as a study area to establish re mote sensing inversion model of soil moisture based on Landsat ETM＋image by the soil moisture spec- trum method and the regression analysis, as well as the model was verified. The results showed that the model precision was above 81~ by executing precision inspection. The study could provide method of mo- nitoring soil moisture quickly and timely in large area for Hetao Irrigation district.
