Zaštita prirode life and nature primena GIS-a i ERM modela u proceni intenziteta erozije zemljišta u slivu reke Lugomir

Abstract

An adequate land management is one of the greatest challenges in the field of environment. In this paper, the assessment of the intensity of soil erosion in the Lugomir river basin (central Serbia), which has an area of 451 km2, was investigated. The first step in this study is related to the collection of geospatial data and their application in geographic information systems (GIS). The second step is the evaluation of all the criteria required for the calculation of the intensity of erosion (Z) using the Gavrilović method: geological base, land use method, state of vegetation and slope of the topographic surface. The third and final step is obtaining a synthesis map, i.e. a map of erosion intensity and interpretation of the obtained results. Based on the EPM model and calculations in GIS, it was established that 41.4% of the territory of the basin is subject to medium and strong erosion. The average erosion coefficient is 0.409, that is, it belongs to the weak erosion class. The study offers a description of the application of modern technologies in determining the degree of erosion in the territory of the Lugomir basin, and the obtained results can be applied for more adequate management of water resources and soil, as well as for nature protection and sustainable planning of forest ecosystems.
