Abstract
The study was based on the research completed by the authors. The research for the study was based on the use of a relatively broad selection of cartographic materials as well as scientific literature. The characteristics of 17 kinds1 of natural landscapes and 31 variations of landscape of the Chełmno-Dobrzyń Lakeland, Ursziilewo Plain and the neighbouring Vistida and Drwęca Valleys were described. The origins of the terrains provided the main criteria used for identifying the kinds of landscapes. A relationship to the appropriate sort of natural landscapes (glacial, glacioaquatic, aeolian, depression, river and channel valley), and the morphology and hypsometry of the land reliefs (flat plains, undulated plains, hills, ridges, high slopes) determined the terrain origin. When identifying the different variations of natural landscape, the following were of major importance: the land relief (defined as the kinds of landscape), and lithology of the surface deposits, and land use (forests, arable land, meadows and pastures). Urban areas and large excavations were described separately. Similar distinctions of kinds and variations of landscape used by other authors, are noted elsewhere.
Keywords: typology and evolution of natural landscapes, kinds and variations of landscape, phys-ico-geographical mesoregions

Levels in subglacial channels and their significance in determining the channel origin and evolution
Geographia Polonica (1988) vol. 55, pp. 113-128 | Full text
Abstract
The present author points out that only in some large subglacial channels of the Dobrzyń Lakeland there are glacial till horizons indicative of ice-sheet participation in their formation. In subglacial channels cut out subglacially by glacial water, which prevail in the study area, the horizons are likely to occur as fluvioglacial erosional levels. There are fluvioglacial accumulative horizons along subglacial channels where outwash water flowed away, independently of their origin, while kame terraces occur in some of large channels filled up with dead ice. There exist lake terraces in subglacial channels in which there were or still are lakes, whereas fluvial terraces are present in considerably transformed channels. Analysis of these levels reveals the origin of channels and allows establishment of channel evolution stages during the Lateglacial and Holocene.
