Hydrochemistry of rich fen and water management

摘要: Abstract Rich fen, a type of wetland characterised by calciphyte species, is strictly related to high groundwater levels with contents calcium and bicarbonate ions in the soil water. fen threatened changes water management surrounding areas. With view preserve suitable conditions for rich conservation management, hydrochemistry small was studied relation its hydrology. In order know whether are maintained impeded drainage or seepage from aquifer balances have been calculated. Chemical made decide originate local on-site sources weathering processes subsequent fen. Vegetation development appeared be conditioned upward having low redox status containing ions. capable retain topsoil only if can on level that prevents pyrite oxidation. Conservation must include regional prevent hydraulic heads fall such no take place. Local should directed decrease combination stimulating surface runoff.
