    Soil Water Retention and Gross Primary Productivity in the Zábrod area in the Šumava Mts

  • Original language description

    The synergy between hydrologic extremes, plant transpiration, gross primary productivity, and soil water retention was studied in the experimental area Zábrod ? meadow in the Šumava Mts. (Bohemian Forest) during vegetative seasons of 1983?2000. Heat balance, potential and actual transpiration, entropy production and gross primary productivity were evaluated. It was found that global radiation, precipitation amount and the soil water retention are the crucial factors determining hydrologic pattern and gross primary productivity. Insufficient soil water retention leads to small entropy production by evaporation and small gross primary productivity, which results in the extremalization of the hydrologic cycle. On the other hand, in the case of sufficientsoil water retention, high entropy production by transpiration and high gross primary productivity leads to the stability of the hydrologic cycle.

    Retence půdní vody a hrubá primární produktivita na ploše Zábrod na Šumavě

  • Czech description

    Na experimentální ploše Zábrod ? louka byla v letech 1983 ? 2000 studována synergie mezi hydrologickými extrémy, transpirací rostlin, hrubou primární produktivitou a retencí vody v půdě. Byl vyhodnocena tepelná bilance, potenciální a aktuální transpirace, produkce entropie při evaporaci a hrubá primární produktivita. Bylo zjištěno, že rozhodujícími faktory, které determinují produktivitu fytomasy, jsou globální radiace, množství srážek a retence vody v půdě. Nedostatečná retence vede k nízké produkci entropie a nízké produktivitě fytomasy, což způsobuje extremalizaci hydrologického cyklu. Avšak pokud je dostatečná zásoba vody v půdě, pak vysoká transpirace, vysoká produkce entropie při evaporaci a vysoká primární produktivita stabilizuje hydrologický cyklus.
