  • Hornovltavsk luh- seversk niva ve stedn Evrop?Ivana Bufkov

    Sprva NP a CHKO umavaivana.bufkova@npsumava.cz

  • Lokalizace zem

  • Jedna z nejzachovalejch nch niv v esk republice pulsujc vliv pravidelnch zplav - zachovny funkn vztahy mezi ekou a okoln nivou - dynamick a nestl prosted - obnova ranch sukcesnch stadi - uptake ivin, atd. pirozen funkce v krajin - retence vody v krajin, snen a zpomalen postupu povodovch vln - zachycen ivin - centrum biodiverzity, migran cesty

  • Horsk niva s geomorfologi ninnch tok irok ploch dol (sklon do 1,2) pomrn irok n niva (a 1,5km) meandrujc tok etn odstaven ramena, tn, backwaters, vrazn laterln dimenze n nivy horizontln lenitost

  • Specifick charakter vegetace Vzkumn projekt:

    Vazby mezi vegetac a abiotickm prostedm v horsk n niv
