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 theestablished soil-landscape communications and the developed system of the landscapeindication the essence of which consists of the use of external characteristics of a landscapeas its indicator of components remote for direct supervision (in our case - soils).Landscape indication proves the soil maintenance of contours of a factorial basis. Theoffered soil-landscape and intrasoil communications (SLС), can be used both directly formapping and typification of elementary soil structures (ESS) and for studying agrogenetransformation of a soil cover.In the process of escalating the information, its intermediate analysis at a preliminarystage, and also at field works and finishing registration period, the period of themodel of soil-landscape communications is developed. The model means filling the allocatedlandscapes with the soil maintenance, thus soils are considered as the soilgeologicalbodies evolving together with a relief and a landscape.At studying the structure of a soil cover (SSC) the likelihood model of soil-landscapecommunications is accepted: a relief (mesorelief elements) - ESS with the use of the informationreceived on detailed keys. Such model most adequately reflects differentiationof a soil cover in communication with mesorelief elements. In it the requirement of conceptSSC - conformity of hierarchical levels of a soil cover and a relief is observed. If wetry to establish connection of soils with mesorelief elements on individual cuts, objectivityof model SLС will decrease. She will be suitable for indication of prevailing soils, butwill grease a picture of spatial heterogeneity of a soil cover which is defined not onlyprevailing, but also accompanying components.The established landscape-indicator dependences allow to increase reliability of allocationof areas ESS and accuracy of a card as a whole. Thanks to "the structural" approachconsistently 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.
