Abstract:Na podlagi baze Uprave RS za zaščito in reševanje smo analizirali, kako različni talni dejavniki (globina, organska snov, tekstura, sposobnost tal za zadrževanje vode ter razred/tip tal) vplivajo na pojavljanje zemeljskih plazov v Sloveniji. Sloje smo analizirali v programskem okolju GIS. Na osnovi statističnega %2 testa homogenosti smo ugotovili statistično značilen vpliv vseh talnih lastnosti, vključenih v analizo. Glede na globino tal se plazovi statistično značilno pogosteje od pričakovanega pojavljajo na tleh, globine 0%70 cm, glede na povprečno organsko snov gornjega horizonta tal na slabo in srednje humoznih tleh, glede na teksturo tal v razredih srednje težkih ter srednje težkih in težkih tal, glede na efektivno poljsko kapaciteto pa v srednjem razredu (80%150 mm). V primeru talnih tipov smo ugotovili, da je matična podlaga eden izmed glavnih vplivnih dejavnikov. V prihodnje predlagamo uporabo analiziranih talnih dejavnikov pri izdelavi kart verjetnosti za pojavljanje zemeljskih plazov, ki bi bile podlaga za izločanje varovalnih gozdov, ki ščitijo pred zemeljskimi plazovi.

Title:The impact of soil properties on landslide occurrence in Slovenia
Abstract:Using landslide database, we tested how different soil properties (soil type, depth, organic matter, texture, soil bonitet number and effective field capacity) affect the landslide occurrence. Our using the X2 test of homogeneity, the results showed that all the tested soil properties have a statistically significant impact on the landslide occurrence. In the case of the soil type analysis, we concluded that it correlates highly with the bedrock analysis. Analysis of the soilʼs depth showed that landslides occur more often than expected on the soils with depth class 0-70 cm, organic matter content classes 1-4 %, texture classes with moderately fine and moderately fine to fine texture, and soil water holding capacity 80-150 mm. We intend to use the tested soil properties for creating landslide hazard maps in the future analysis. These maps could apply as a tool for zoning of the protection forests that protect from the landslides.
