Analysis of the energetic exchange processes within the two different forest ecosystems

Popis výsledku v původním jazyce

The energy exchange above floodplain forest ecosystem and spruce monoculture ecosystems was measured in Moravia during the years 1988 and 1989. The results showed that a floodplain forest ecosystem with good access to ground water evaporated more rapidlythan a spruce monoculture. Greater flux of energy was recorded in a diurnal variation of sensible heat flux (65% of net radiation), in contrast with the spruce monoculture. The floodplain forest latent heat flux proportion to net radiation was found to be variable within the growing season; in the middle of the vegetation period (from June to August) it reached the value of about 70%, by the end of October it was only 20%. The estimation of the floodplain forest actual evapotranspiration was possibl e over most of the season, the actual evapotranspiration reached its maximum of 0.72 mm m-2h-1 one hour after the maximum net radiation. It was not possible to measure the spruce monoculture latent heat flux over the whole season, due to the
