Vpliv vetra na nastajanje tal v Evropi in Sloveniji

diplomsko delo

Abstract

Vpliv vetra pri nastanku tal je še precej neraziskano področje. Cilj diplomskega dela je predstaviti vse pomembnejše vplive vetra na nastanek in izvor tal. Na območju Evrope so imele velik vpliv ledene dobe. Vplivale so na več dejavnikov: pokritost tal, moč in smer vetrov, količino padavin, preperevanje kamnin, ter na vlažnost in strukturnost/povezanost tal. Vse to je vplivalo na erozijo in premeščanje delcev v večjem obsegu kot v današnjem času. Ledene dobe sovpadajo z nižjo gladino morja, kar je pomenilo, da je velik del osrednje Evrope dobil prašne delce tudi iz območja, ki je sedaj pod morjem. Drugi pomemben vpliv imajo delci, ki jih prinese iz drugih celin, predvsem iz območja severne Afrike, Sahare. Raziskovalci predvidevajo, da je veter močno vplival na nastanek tal južne Evrope, tudi v srednji Evropi je ta vpliv še opazen. Na osnovi pregleda literature lahko sklepamo, da podobno velja tudi za Slovenijo. V primorskem delu se verjetno bolj pojavlja vpliv afriških puščav, medtem ko v ostalih delih Slovenije veter raznaša prah iz gora v nižje ležeče dele.

Secondary title:	Aeolian contribution at soil formation in Europe and Slovenia
Secondary abstract:	Aeolic effect on the soil formation is still quite unexplored area. The goal of my Thesis is to present all the major impacts of wind and the source areas of the particles, which form particular soil. The impact of ice age has an important role in Europe. It influences ground coverage, wind speed and its direction, the amount of precipitation, soil weathering, soil moisture and soil structure. All factors contribute to dust transportation. There was also lower sea level in ice age, which resulted in erosion of open area, which was later on deposited in central Europe. Another important impact on European soil formation is that wind transported particles from other continents, especially from North Africa area, the Sahara desert. This was especially important in soil formation in southern Europe and is still noticeable in central Europe. Both impacts also apply to Slovenia. In the coastal part, the influence of African deserts is more pronounced, while in other parts of Slovenia, the wind blows dust from the mountains to the lower area.
