Regularities of quantitive indexes of spectrum reflective capacity of drained peat human-transformed soils, determined by contamination of its organic matter and residual ash elements. It was given morphologic diagnostic of investigated soils which were formed on objects of drainage according to a new soil classification. It was established both indexes spectrum reflective capacity of upper horizons and profile as a whole serve for the release of 3 species of drained peat human-transformed soils in soil classification. As a result of research it is necessary to divide drained peat soils on agro-peat and degro-peat soils with allocation in last three species under the content of organic matter (ОM) (peat-mineral ОM =50,0-20,1%, mineral residual-peat - ОВ = 20,0-5,1% and mineral postpeat - ОВ 5,0%) is established. Legitimacy of such soils allocation is proved proceeding from their properties and profile structure causing their reflective ability. Spectrums of reflection of light of the top horizons of agro-peat soils and degro-peat soils though are presented by typical smooth curves, but differ on character of distribution: for spectral curves of agro-peat soils minor alteration of ordinates on all spectrum is characterized, and for degro-peat soils - smooth increase in factor of reflection with increase in lengths of waves. Limits of a variation of spectral parameters of soil profiles and also rather essential correlation dependences between integrated coefficient of reflections and ash content have confirmed legitimacy of allocation of three specific levels of degro-peat soils. Distinctions in spectral reflective ability of investigated soils can be used as objective parameters at their studying of morphogenetic attributes
