Description
  • Zabývali jsme se fungováním krajiny z hlediska toků energie v oblasti těžby hnědého uhlí na severu České republiky. Vycházeli jsme z předpokladu, že změna land use se odráží i v energetických tocích. Z energetických toků v krajině se naše pozornost soustředila zejména na podíl dopadající sluneční energie, která se v procesu evapotranspirace přemění na latentní teplo. Zájmové území zahrnuje hnědouhelný lom ČSA (14km2) a blízké okolí (celkem 53.1 km2). Data land use byla získána terénním mapováním. Každé jednotce land use byla přiřazena průměrná hodnota evapotranspirace pro vegetační sezónu. Tyto hodnoty byly získány z literatury. Dále byly získány teploty krajinného krytu a vypočítány hodnoty vlhkostního indexu z družicových dat Landsat TM pro celé zájmové území. Tato data do značné míry vypovídají o podílu přeměněného dopadajícího záření na zjevné teplo. Dále jsme ověřovali předpoklad nepřímé úměrnosti mezi evapotranspirací a surface temperature a přímé úměrnosti mezi vlhkostním indexem a evapotransp (cs)
  • Functioning of the landscape was evaluated from the point of view of energy flow in the brown-coal mining area in the northern part of the Czech Republic. We assumed that the change of land use was also reflected in energy flows. Our attention was focused mainly on the proportion of incident solar energy that is changed to latent heat within the process of evapotranspiration. The area of interest included brown-coal opencast (14 km2) and its close surroundings (53.1 km2). The land use data were acquired by terrain mapping. An average value of evapotranspiration for growing season was assigned to each land use unit. These values were obtained from the literature. We also obtained surface temperature and surface wetness from Landsat TM satellite data for the whole area of interest. These data present a good evidence of incident radiation converted to sensible heat. Furthermore, we verified the relation between evapotranspiration and surface temperature, and between wetness index and evapotranspiration.
