Evaluation of geodiversity of landform of some fragments of young glacial landscape of Chełmińsko-Dobrzyński Lake District)
Recently, geodiversity has been defined as the changeability of all the abiotic elements of the natural habitat. It can be considered in the context of being a feature of a single geocomponent, a single geocomponent, or the whole natural habitat. According to A. Kostrzewski (1998, 2011), the relief’s geodiversity is “the actual diversity of the Earth’s surface, taking into account the morphogenetic zones, types of relief, and compounds of forms, or single forms of the relief”. At present, the most extensive research of geodiversity takes place in the areas of spatial identification and the evaluation of geodiversity (Kot, 2006; Serrano, Ruiz-Flaño, 2007a, b, c; Hjort, Luoto, 2010; Kostrzewski, 2011), geoconservation (Geographica Helvatica, 62, 3, 2007), geotourism (Reynard et al., 2007), or search of its indicators (Zwoliński, 1998) and its monitoring (Kostrzewski, 2011).
The aim of this article is to assess the usefulness of the used method of point classification for determining the spatial geodiversity in the detailed scales (1:25 000 and 1:10 000), delimiting the factors that exert an influence on the outcome of the evaluation. It is important to demarcate the most diverse areas, which are the most meaningful for the environmental protection as well as for the development of tourism. The research conducted on the area of the representative basin (in the vicinity of Toruń), can also be of validity for the creation and implementation of the geodiversity program within the framework of ZMŚP (Integrated Monitoring of the Natural Environment Program).
The research areas consists of the Struga Toruńska representative basin, which is tested in the Integrated Monitoring of the Natural Environment Program (Struga area) and a part of the Górzno-Lidzbark Ladndscape Park (Bryńsk area). According to physico-geographical regionalization by J. Kondracki (1998), the basin is situated on the border of southern part of physico-geographical mesoregion Chełmno Lakeland (315.11) and Bryńsk area on the
border of third mesoregions: Chełmno Lakeland (315.11), Lubawa Elevation (315.15) and Urszulewo Plain (315.16).
