Changes of the environment of the lower Luciąża river valley in holocene
Languages of publication
The subject of the research is the lower Luciąża river valley, located in the central part of
Poland. Differentiated geological structure, resulting from base tectonics and relief inherited
from middle-polish ice sheets, influenced significantly natural complexity and differentiation of
human influence on the valley. In the result of warmth and flora's incoming, a change in the
river character has occurred (from the braided to the meandering one), already in Late Glacial,
probably in AllerOd (before 10 9Z0 BP).
The frrst fossil mineral record of human activity in the valley is a frreground level in the
meander residual in Kludzice, dating from 3 6Z0 BP (the turn of the Bronze and Iron Ages).
Partial burning of the valley resulted in cover plant conflagrations and intensified surface flow. The
climate cold trend in Subboreal (5 OOO-ZZOOBP) increased wind impact. On the deforested
bottom terrace sandy aeolian covers had formed before Subatlantic (until Z 200 BP). In Subatlantic
(l 330 BP), organic sediments and sandy alluvial soils were created, as a result of climate warming.
In historic times the man influenced the valley ever more intensively. Settlements were build, for
example the embanked one in Rozprza, dated at 7t1l century. One of the main transportation
routes of the Piast monarchy also led through the valley. The period of the Little Ice Age
(1450-1750) and the then climate cooling and raising of the ground water level made people leave
the valley and enter the plateau area. Luciąża river has been used for energy production.
Largest changes have occurred during the last 100-170 years. The construction of railways
and modem roads, deforrestation and building of two reservoirs - Sulejów and Cieszanowice
artificial lakes has begun. Economic activation during and after the 2nd World War (melioration
and hydrotechnical constructions) was of a great importance.
Przedmiotem rozważań Autorki w niniejszym artukule jest rozwój doliny dolnej Luciąży
w holocenie. zarysowane zostały również kierunki i rodzaj zmian, jakich dokonał człowiek
w dolinie w różnych okresach, począwszy od neolitu do czasów współczesnych. Wskazano na
silny związek człowieka, jego siedlisk w dolinie w okresach historycznych. Przedstawiono
zabudowę hydrotechniczną doliny trwającą od średniowiecza, zmiany użytkowania ziemi, np.
wylesianie przypadające na XIX w. i na nasiloną antropopresję w dolinie w ciągu ostatnich
30 lat związaną z budową dwóch zbiorników wodnych - sulejowskiego i cieszanowickiego. Na
podstawie własnych badań oraz na podstawie literatury nakreślono dalsze zamierzenia badawcze
w ujęciu kompleksowego prześledzenia ewolucji systemu Luciąży w ostatnich 10 000 lat.
