The main objective of this paper is to represent the hierarchical structure of an environment by using two concepts: typology and regionalization. The Płock Region (1,766.95 sq. km) and transect crossing this area (796.2 sq. km) is the research location. It was divided into 710 individual landscape units (319 in the transect border). The existing physicalgeographical regionalization, including macro-, meso-and micro-regions, was elaborated using a deductive (top-down) method, which was

... ted by a more detailed regionalization, obtained by an inductive (bottom-up) method called analysis of borders (Richling 1976). The study area was divided into more detailed sub-regions: first-level regions (87 units), second-level regions (36 units) and third-level regions (9 units). In fact, the landscape structure of third-level regions is similar to microregions. This is proof of the complementary nature of the two approaches -deductive and inductive regionalization, and the hierarchical landscape structure.
