Významnosť vegetácie mäkkých lužných lesov z pohľadu ichsocio-ekonomických funkcií v alúviu Váhu

摘要

In the lowland of Slovakia there were identified only some fragments of the floodplain forests in the alluvium of the river Váh. In this paper there are presented our results of the assessment of the significance of the floodplain forest vegetation in the alluvium of the bottom reaches of the river Váh, on the localities with different groundwater level. We assessed selected ecological and structurally attributes of vegetation, productivity, and crop growth rate of the herbaceous layer. We can state that lower biomass production in the locality with lower groundwater level is accompanied by higher species diversity of the herbs. The herbs use higher groundwater level on the remains of the biomass productivity. The species diversity was reduced. As far as utilitarian functions of the floodplain forest are concerned, the vegetation reached the values of significance to socio-economic function in the landscape from median to extraordinarily high. We have found that the micro-climatic and selected soil protective functions of the floodplain forest in open landscape are of extraordinarily high value of significance.
