Distribution of Solar Energy in Agriculture Landscape: Comparison Between Wet Meadow and Crops

摘要: This study examines the impact of plant cover on water and energy exchange between land atmosphere in Třeboň Biosphere Reserve, Czech Republic. Energy fluxes, evapotranspiration evaporative fraction were determined over typical crops agriculture landscape compared with fluxes an adjacent wet meadow. The results show distinct differences heat these ecosystems. Diurnal average difference rates for days high irradiance meadow arable ranged from 1.1 mm day−1 to 3.4 day−1. Furthermore, C3 (rapeseed) C4 (cornfield) was about 2.3 Analysis thermovision pictures showed that temperature variation reached 9 °C ploughed field meadows at time maximum intensity solar radiation. Heat (sensible flux) greater lands, while (latent stronger displayed more than 100 % available released by through due advection dry air surroundings. Wetlands equal or even inverse vertical profile, whereas corn wheat noticeable higher soil surface comparison stand surface. Therefore, we suggest introduction wetlands agricultural is one most important instruments management balance landscape.
