We want to find out, how water resources in Sotla river basin contribute to soil characteristics. This knowledge is important for land use orientation and consequently for soil protection. For this purpose we studied Sotla river basin as region, which is divided on five hydrographical areas. We compared them according to water and pedological characteristics considering land use. The accent was on GIS methodology. Sotla river basin is located along Slovenian-Croatian border and is very asymmetric. The river network is very dense, present are also many standing waters. From land use predominate forests followed by grasslands, fields, built-up areas, vineyards, orchards, trees and bushes, swamps and marsh grasslands. From the soils predominate eutric and distric brown soils, in hills rendzina, ranker and brown soils on limestone. Vineyard sites cover anthropogenic soils. In river valleys are spread riverine soils on clay, gleyed and pseudogleyed soils. Surface waters in Sotla river basin are highly subjected to human act and have great influence on soils. That reflects in land use. It can be recognized in high percent of agriculture fields, the most extensive on holocen flat lands along rivers Sotla, Mestinjščica and Bistrica, where predominate hydromorfic soilsPrst nastaja in se razvija na stiku prepletanja in medsebojnega delovanja vseh sestavin pokrajine, tudi hidrosfere. Ugotoviti želimo, kako vodni viri v porečju Sotle vplivajo na značilnosti prsti, saj je poznavanje teh zakonitosti pomembno za usmerjanje rabe tal in s tem za varovanje prsti. V ta namen smo porečje Sotle razdelili v pet hidrografskih območij in jih primerjali glede na vodne in pedološke značilnosti ter pri tem upoštevali značilnosti rabe tal. Glavni poudarek smo dali metodi analize z GIS-i. Porečje Sotle leži ob slovensko-hrvaški meji in je izrazito asimetrično. Rečna mreža je gosta, prisotne pa so tudi številne stoječe vode. Od rabe tal prevladuje gozd, sledijo travniki in pašniki, njive, pozidana zemljišča, vinogradi, sadovnjaki, drevesa in grmičevje, mokrišča in barjanski travniki. Od prsti prevladujejo evtrične in distrične rjave, medtem ko hriboviti svet prekrivajo rendzine, rankerji in rjave pokarbonatne prsti. Vinogradniške lege označujejo rigolane prsti, v rečnih dolinah pa prevladujejo obrečne prsti na ilovnatem aluviju, oglejene in psevdooglejene prsti. Površinske vode, ki so v veliki meri podvržene človekovemu delovanju, imajo v porečju Sotle velik učinek na prsti, kar se odraža tudi v rabi zemljišč. Tako se v porečju Sotle pojavlja velik delež njivskih zemljišč, ki so najobsežnejša na holocenskih ravnicah ob Sotli, Mestinjščici in Bistrici, kjer prevladujejo hidromorfne prstiTEXTznanstveno časopisjejournalsSlovenian National E-content AggregatorNational and University Library of SloveniaUniverza v Mariboru, Filozofska fakulteta
