Z metodyki badań krajobrazowych w Tatrach

In order to verify the formalized method of delimitation of physico-geographical units of the „uroczysko” ¹ type in the mountainous landscape, three M.A. theses were done in the Tatra Mts. The „uroczysko” types were distinguished by correlating the properties related to the relief, geological substratum and land covering. The work by W. Lewandowski concerned a high situated little valley (Dolina za Mnichem) and was made on a scale 1 : 2000. A total of 18 „uroczysko” types were distinguished within the lower part of the valley, each of which was characterized in terms of the relief, substratum, land covering and soils. P. Żarski dealt with the bigest valley called the Valley of Five Polish Lakes. On a base map representing a mechanical magnification of a 1 : 10 000 map to a scale of 1 : 4 000 a number of analytical maps were elaborated and a total of 19 „uroczysko” types vere distinguished. The imperfect base map, however, which made mapping of many details impossible, is responsible for the fact that the obtained picture is unsatisfactory. The third research work done by M. Żarski concerned the Trzydniowianski Wierch mountain massif in the Western Tatras. A 1: 10 000 scale was used here and an assumption was made that individual vertical belts correspond to the terrain types (ecochores). The „uroczysko” types were distinguished individually in each belt. For this reason, as well as in view of a considerable variability of the rock bed, as many as 57 range type were distinguished. Each type was characterised in the paper from the standpoint of relief, geological structure, vegetation, soil types and hydrological regime. The tests made appear to support the view that also in the mountain area the relief, land covering and ground may be considered as key factors in delimiting the types of „uroczysko”. In conclusion a proposal was made as to the morphometric classification of the relief of the upland and mountainous areas, and a point was made of the grouping of „uroczysko” -types to obtain higher-order classification units.
