The importance of wetlands in the energy balance of an agricultural landscape

Popis výsledku v původním jazyce

Abstract Energy fluxes, including net radiation, latent heat flux and sensible heat flux were determined on clear days during the vegetative period in four types of land cover: wet meadow, pasture, arable field, and an artificial concrete surface. The average net radiation ranged between 123 W m-2 at the concrete surface and 164 W m-2 at the wet meadow. The mean maximum daytime latent heat ranged between 500 and 600 W m-2, which corresponds to an evapotranspiration rate of about 0.2 g m-2 s-1 under theprevailing conditions of the wet meadow. The results demonstrated that the wet meadow dissipated about 30% more energy through evapotranspiration than the field or the pasture, and up to 70 % more energy than the concrete surface. The evaporative fraction indicated that more than 100% of the energy released by the wet meadow was dissipated through evapotranspiration; this was attributed to local heat advection. Wetland evapotranspiration thus contributes significantly to the cooling of a
