对遥感像元尺度上互易原理和Planck定律“视在失效”的研究表明其共同原因在于此尺度上地表空间的复杂性 .从而这些原理和定律不能作为思维定式在对地遥感中误用 .相反 ,对这些原理或定律的尺度效应及其规律性应作大胆的探索 Studies of reciprocity at remote sensing pixel scales and “apparent failure” of the Planck’s law show that the common cause is the complexity of the surface space at this scale, so that these principles and laws can not be misinterpreted in land-based remote sensing as a way of thinking. On the contrary, the scale effect and regularity of these principles or laws should be boldly explored
