Vliv využití vegetačního krytu na energetické toky a evapotranspiraci na příkladu dvou malých povodí.

Original language description

In this study we evaluated energy balance and evapotranspiration of a herbaceous wetland and a drained semi-intensive pasture using seasonal meteorological measurement and a remote sensing. We assessed data from the growing season 2007. The results showed that seasonal amount of net solar radiation was higher in the wetland. Contrary to our assumption, the monthly sums of the latent heat used for evapotranspiration was higher in the pasture. We suppose this was due to higher mean wind speed and higher advection of warmer and dryer air in the pasture and due to locally specific characteristics of the stand. Evaporative fraction and latent heat flux of two small catchments (Mlýnský ? pasture; Horský ? wetland, forest) were compared using remote sensing technique (Landsat 5 TM; 25th July, 2007). The analysis of the remote sensing data showed higher latent heat flux in the Horský catchment. The mown meadows with lower latent heat flux were apparent on the satellite images in both studied c
