摘要

The distribution of zonal soils from Jijiaa€?s upper catchment is the result of the development in time of all soil forming and evolution processes. The problems regarding the soil cover and its capitalization become often a€?complicateda€?, being constantly subjected to the land use. For this paper, was used the methodology for establishing classes of land use based on the Romanian System of Soil Taxonomy (2012) nomenclature. Based on GIS software was conducted the assessment and classification, by statistical and spatial methods, of soil basic features in relation to the present land use. In terms of pedogenesis, Jijia upper catchment represents an area with high complexity in relation to the environmental variability. On the overall is confirmed the area-elevation distribution of the main types and soil classes, marking the transition from Chernisols (through Phaeozems) to Luvisols. For the entire basin, forested areas exceed the national average (36% of the studied zone), to these being added the territories under constructions that occupy considerable area (11%). Regarding the land used as arable (27%), it can be pointed out the strong capitalization of Chernisols (Chernozems and Phaeozems), including also those located on slope conditions. Uncontrolled extensions on stable terrains with high pedological potential creates an anthropogenic pressure on the soil background, the arable lands being specific also to some areas with soils less favorable (Luvisols, formed and evolved in the forest, but gradually taken into the agricultural utilization). Moreover, in this way it is noticed an incresead percent of territories affected by landslides and other current geomorphological processes.
