Usage of landshaft-indicator communications to study the structure of their soil cover on the example of the southwestern part of Academgorodok of Tomsk
The allocation and the diagnostics of soil areas are mainly made on the basis of the established soil-landscape communications and the developed system of the landscape indication the essence of which consists of the use of external characteristics of a landscape as its indicator of components remote for direct supervision (in our case - soils). Landscape indication proves the soil maintenance of contours of a factorial basis. The offered soil-landscape and intrasoil communications (SLС), can be used both directly for mapping and typification of elementary soil structures (ESS) and for studying agrogene transformation of a soil cover. In the process of escalating the information, its intermediate analysis at a preliminary stage, and also at field works and finishing registration period, the period of the model of soil-landscape communications is developed. The model means filling the allocated landscapes with the soil maintenance, thus soils are considered as the soilgeological bodies evolving together with a relief and a landscape. At studying the structure of a soil cover (SSC) the likelihood model of soil-landscape communications is accepted: a relief (mesorelief elements) - ESS with the use of the information received on detailed keys. Such model most adequately reflects differentiation of a soil cover in communication with mesorelief elements. In it the requirement of concept SSC - conformity of hierarchical levels of a soil cover and a relief is observed. If we try to establish connection of soils with mesorelief elements on individual cuts, objectivity of model SLС will decrease. She will be suitable for indication of prevailing soils, but will grease a picture of spatial heterogeneity of a soil cover which is defined not only prevailing, but also accompanying components. The established landscape-indicator dependences allow to increase reliability of allocation of areas ESS and accuracy of a card as a whole. Thanks to "the structural" approach consistently realised in the present work, for transition the base is prepared for GIStechnologes. Ordering of soils, the personal computer is included in the algorithm of mapping, factors, and also soil communications - indicators and their quantitative estimation.
