Description:

Water resources are usually treated as potential resources, directly exploitable by human population on the Earth. Among them, surface water and groundwater can be effectively managed for operational use. Soil water which belongs to the class of subsurface water represents the major volume of terrestrial water resources. The concept of soil water resources as a water source for biosphere was introduced recently by Budagovsky (1985) and is related to the fact, that the soil water is the most important factor of the existence and development of terrestrial vegetation. As a measure of soil water resources, Budagovsky proposed the evapotranspiration rate from the land surface during the frostless period representing the sum of water evaporation by soil and transpiration from stomata of the leaves of terrestrial plants. The primary importance of soil water is in its role as a source of water for biosphere, for the first stage of trophic chain on the Earth. In this review, the role of soil water in biotic and abiotic cycle on the Earth is discussed. Possible directions of the future study of soil water resources in relation to the environment are proposed. and Za zdroje vody na Zemi sa považujú spravidla tie potenciálne zdroje, ktoré môžu byť využité ľudstvom priamo. Priamo môžu byť využité povrchové a podzemné vody. Najväčší objem vody súše na Zemi je reprezentovaný vodami podpovrchovými. Budagovskij (1985) navrhol koncepciu pôdnych vôd ako zdroja vody pre biosféru; táto koncepcia je založená na skutočnosti, že pôdne vody sú najvýznamnejším zdrojom vody pre suchozemskú vegetáciu. Ako mieru zdrojov pôdnej vody Budagovskij navrhol evapotranspiráciu z pevniny počas bezmrazového obdobia, ako súčet výparu z pôdy a transpirácie cez prieduchy suchozemských rastlín. Najvýznamnejšou úlohou vody v pôde je to, že je zdrojom vody pre biosféru, pre prvú časť trofického reťazca na Zemi. Táto práca pojednáva o úlohe vody v pôde v biotickom a abiotickom cykle na Zemi. Sú naznačené tiež možné smery výskumu zdrojov vody v pôde v kontexte k biosfére.
