The paper presents the results of the studies of diversity of natural environment of the Pilica river basin near Wielkopole. The studied transect covers 5 km2 and stretches from a local watershed in a zone of outcrops of Mesozoic bedrock to a floodplain of the Pilica river. Within this area, morpholithohydrotopes were distinguished and in several locations grain size and agrochemical features of soils were determined. The description of the landscape structure was supplemented by a landscape cross section depicting geocomplex types, land use, geology, groundwater level and some soil profiles. In the description of morpholithohydrotopes the relation between habitat potential and a land use pattern within the distinguished land units was stressed. The soil profiles were presented, including grain size and chemical features of soils.

W artykule przedstawiono wyniki badań dokumentujących zrozll1cowanie środowiska przyrodniczego terenów nadpilicznych w okolicach Wielkopola. Dla transektu badawczego o powierzchni 5 km2, poprowadzonego od lokalnego działu wodnego w strefie wychodni podłoża mezozoicznego do dna doliny Pilicy, przeprowadzono delimitację geokompleksów częściowych - morfolitohydrotopów. Wykonano również szereg odkrywek w celu udokumentowania właściwości granulometrycznych i agrochemicznych gleb. Charakterystykę struktury przestrzennej wyodrębnionych jednostek uzupełniono przekrojem krajobrazowym, wzdłuż którego przedstawiono typy geokompleksów, użytkowanie ziemi, styl budowy geologicznej, położenie zwierciadła wód podziemnych oraz wybrane profile glebowe. Przedstawiono charakterystykę profIli glebowych oraz zamieszczono tabele przedstawiające cechy granulometryczne i chemiczne badanych gleb.

Basic surface features of the Łask Interfluve near Zduńska Wola originated during the Wartanian ice-sheet areal deglaciation. The ice-sheet waning resulted in formation of groups of crevasse landforms such as kame plateaux, kame hillocks, kame terraces and melt-out depressions. The post-Wartanian morphogenesis increased diversity of the relief by rejuvenation of most of buried valleys, by cutting new valleys and raising the interfluve surface with aeolian sheets and dunes. Sand and silt were deposited in melt-out depressions. The depressions had initially functioned as closed depressions and had formed a local base level. They were incorporated into a valley network presumably at the end of the Vistulian glaciation. Blocks of dead ice melted gradually and it has led to the formation of flattenings in the melt-out depressions bottoms. The flattenings are 2-3 m high and have short gentle slopes. These slopes and the slopes of the melt-out depressions are cut with dells and basin-like valleys. Few of the cuttings continue their direction as barely perceptible, shallow flat-floored valleys drained by perennial or intermittent watercourses. In the Holocene eight types of geocomplexes with stable matter and energy structure were formed, as a result od natural processes. Man's influence has led to diversification of the environment which can be represented by 19 types of present-day geocomplexes. The 19 types are characteristic of all the melt-out depressions in the environs of Zduńska Wola, but they display a unique mosaic in each depression. It is noteworthy that the depressions function as groups of homolithic geocomplexes. Man-made changes in the depressions result from agricultural land use

Artykuł przedstawia typologię i funkcjonowanie geokompleksów zagłębień wytopiskowych na tle rozwoju paleogeograficznego zachodniego fragmentu Wysoczyzny Laskiej w okolicach Zduńskiej Woli. Uwzględniono w nim naturalne procesy przyrodnicze i antropizację środowiska związaną z użytkowaniem rolniczym.
