对于植被影响土壤水分遥感的大小 ,提出了“光学植被盖度”新概念来衡量 ,并用遥感法进行估测。用分解象元法排除植被干扰来提取土壤水分光谱信息。采用土壤水分光谱法并借助回归分析建立土壤水分遥感的TM数据模型。以此为桥梁 ,建立了AVHRR数据模型 For the size of the remote sensing of soil moisture affected by vegetation, a new concept of “optical vegetation cover” is proposed to measure and estimate with remote sensing method. Vegetation disturbances were extracted by decomposition pixel method to extract soil moisture spectral information. Soil moisture spectroscopy and regression analysis were used to establish the TM data model of soil moisture remote sensing. Using this as a bridge, an AVHRR data model was established
