Abstract: Tle measurements of reflective spectrum Property of the surface features are the research work of the basic theory of the application of remote sensing. The greyness of remote sensing imagary is closely interlinked with the decrees of the reflectivity of surface features. The establishment of the relationship between the reflectivity of surface features and the greyness value of the imagery is a basis for selecting and testing the test operating bands of transducer and is also a research subject needed the carried out on the imagery distinguishableness and the computer interpretation. Following conclusion is summarized on live analysis of the on-the-slot measures spectrum data: a) the bigger of sand grain size, the higher of reflectivity; b) the higher of salt contents in sand soil, the higher of the higher of reflectivity; the lower of salt contents, the lower of reflectivity; c) the increase of the organic matter contents and the metal-oxide means generally the evident decrease of reflectivity.
