Abstract

Nacionalni park „Krka“ poznat je u Hrvatskoj po velikom broju jezera i slapova koje čini rijeka Krka. Nacionalnim parkom proglašen je 24. siječnja 1985.godine. Najpoznatije prirodne ljepote ovog Parka su slapovi Roški slap i Skradinski buk te jezero Visovac koje zajedno s ostalim slapištima i jezerima predstavljaju prirodni krški fenomen. U NP „Krka“ prisutan je recentni proces nastajanja sedre kao rezultat međusobnog djelovanja fizikalnih i kemijskih čimbenika te živih organizama u vodi. Sedra je naziv za kalcijev karbonat (vapnenac) koji se u tekućicama taloži iz vode na različite podloge. Alge i mahovine imaju važnu ulogu u oblikovanju sedre kao i fauna beskralješnjaka. Intenzivno korištenje prirodnih dobara u porječju rijeke Krke, kao što su primjerice vodoopskrba, proizvodnja električne energije za potrebe industrije, prijevoz, ribarstvo te razvoj turizma i rekreacije razlog su za višestruko i višeznačno valoriziranje prostora rijeke Krke. Prioritetna zadaća zaštite je očuvanje kakvoće voda rijeka Krke i Čikole te je nužno izraditi plan upravljanja NP „Krka“ na principu održivog razvoja i zaštite okoliša.

Abstract (english)

National Park „Krka“ is known in Croatia for many lakes and waterfalls, which are made from Krka River. National Park (NP) was declared in January 24, 1985. The most famous natural beauty of this park are waterfalls Roški slap, Skradinski buk and lake Visovac, which together with other waterfalls and lakes, are a natural karst phenomen. NP „Krka“ presents recent travertine formation process as a result of the dynamic process of physical and chemical interactions and living organisms in the water. Travertine is the name for calcium carbonate (limestone) which is deposited on various substrates in running waters. Algae and moss have an important role in the formation of travertine, and also invertebrate fauna. Intesive use of natural resources in the basin of Krka River, such as water supply, electricity production in industry, transport, fisheries, tourism and recreation are the reason for the multiple and ambiguously evaluation of the Krka River environment. The priority task of conservation is to preserve water quality of the Krka and Čikola rivers, and it is necessary to create a management plan for NP „Krka“ on the principle of sustainable development and environmental protection.
