Ocena jako?ci wody i potencja?u ekologicznego ma?ych zbiorników wodnych odbudowanych w krajobrazie rolniczym Wielkopolski

摘要

The study presents assessment of water quality and ecologic potential of artificially reconstructed small, glacial mid-field water reservoirs, rebuilt in 1999-2000, near the village of Nienawiszcz in Rogo?no municipality in Wielkopolska. Assessment was based on research and analysis carried out in 2010-2012. The biological and physical-chemical elements of water, vegetation of aquatic belts and surrounding reservoirs were analysed. The water in the restored reservoirs meets quality requirements for the fish farming and for bathing purposes. Water quality and ecological potential of the reservoirs can be described as good or satisfactory. Rebuilt mid-field ponds had a positive impact on increasing diversity in the agricultural landscape and together with the surrounding vegetation are a buffer for the nutrients running down from fields.
