The frame/skeleton of landscape genetic-morphological structure of the territory is formed by its morphological parts such as land unit and facet combination. All of them determine natural features of landscape complexes and knowledge about which forms the key basis of elaboration, substantiation and implementation of the landscape planning concept and the system of conformable actions. The spatial landscape differentiation and genetic-morphological structure of the research area are being done on a 1:200 000 scales and the tested area was laid within the central part of the Sumy slope-elevated physiographic oblast. The landscape heterogeneity of the area was studied and grounded on the results of field observations, analysis of the textual and cartographic material, aerospace photography interpretation, literary and statistics data interpretation according to the traditional ladnscapeological methodic. The key operating units of landscape genetic-morphological structure within the forest-steppe complexes the Left-Bank the Dnipro river of Ukraine territory, which was reflected in the middle scale cartographic model, are its morphological part (land unit and facet combination). The substance of that cartographic model in a concentrated form is represented in the legend which was created in a form of matrix and reflects classification structural-genetic grouping of the landscape units, its typological hierarchy, and actual landscape complexes nomenclature. The main group of land units is represented by flat watershed, streamside (slope), flat ancient adjacent to a glacier, above flood-lands terrace, flood-lands, and valley-gully types. Thus is visualized and presented in a form of mapping model, legend-matrix to it, and graphical model – graph of similarity and vicinity. The qualitative landscape complexes characteristics which reflect all variety of landscapes land units, facet combinations and compound facet combinations ranks, which developed within the tested research area, are given. Also, an emphasis is placed on the opportunity to practical using obtained results. Keywords: genetic-morphological structure, land unit, facet combination, forest-steppe complex, landscape.
