摘要: Peatland ecosystems cover about 8 % of the study area “Bornhoved Lake Region” (52 km2), 20 which are close to a natural state. Three peatland under different land use (two alder forest, one pasture) with hydrological conditions unflooded, flooded) at Belau were investigated. Hydrology and strongly influenced plant species composition vegetation structure. Furthermore, great differences in water regime eutrophication investigated recorded. The flooded forest showed strong correlation between soil level lake fluctuations, whereas unflooded pasture was mainly characterised by vertical exchange aquifer. Likewise, nutrient situation differed markedly. With respect nitrogen cycle, site affected harvesting fertilisation, sites main inputs resulted from N2-fixation atmospheric deposition while outputs leaching denitrification.
