摘要

The main objective of the present study was to recognise the differentiation of surface formation - horizontal and vertical (including range and thickness of the deposit) - as well as the soil and habitat conditions of the raised bog "Bagno Bruch". In spite of the relatively small area (39,2 ha) this peatland is characterised by big differentiation of habitats as well as by rare vegetation in this region. The average peat thickness for all the deposit was about 90 cm, the average peat thickness for central part of the deposit was about 160 cm, and the highest thickness was 205 cm. Total abundance of the peat deposit was estimated as 380 650 m3. On the foundation of detailed description of diagnostic layers the character of primary and current soil processes was estimated. In respect of water supply "Bagno Bruch" belongs to ombrogenous bogs possessing small basin with impediment outflow. The peat formation in the deposit of "Bagno Bruch" forms the sequence: sand → detritus gyttja/limnogenous mineral sediment/ peat with mineral sediment → (Pino-Sphagneti peat / Eusphagneti peat) → Eriophoro-Sphagneti peat → Eusphagneti peat → (muck). As a result of dewatering in current phase of the transformation of habitat conditions, the mucky areas appeared.
