Abstract:

 

This paper presents the results of the size of settlement in two stratigraphic sections and changes in morphology in four soil profiles between 1974 and 2012 in Polesie Lubelskie. The bed of peatlands classified as a low type, built reed peat with an mean depth of 3 m Sosnowica and 0.64 m Uhnin. The size of organic soil settlement measured surveying, is in the range of 9 cm to 33 cm, while mineral soils from 0 to 4 cm. The average size of settlement bog in Sosnowica was 24 cm in a period of 38 years, giving a reduction of 0.6 cm · year–1, or peat weight loss of 11.5% of total resources. The situation is even worse in the case of peatland in Uhnin, where mineralization and fire peat bog area resulted in a decrease of 36%. Peat mass loss, due to fire, there was 53% of total resources, which corresponds to the reduction of 0.35 cm · year–1. In period 50 years after dehydration is dominated by peat-muck soil a complex medium dry. The values ​​of the correlation coefficient and the error rate indicates the inapplicability of empirical formulas for determining the size of the settlement.
