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.
