Northern Codrii represents a geographic entity in the Codrii Plateau and has a special morphological structure. Also, the wide range of pedological factors determined the formation of a very varied soil cover. Nowadays, a special attention in the soil survey is given to erosion, which is a serious problem both in Northern Codrii as well as on the whole territory of Republic of Moldova. In the current development of Geographical Information Systems, a quantitative assessment and modeling of the process of soil degradation is possible. Thus, LS-factor is a combined indicator of the L -factor, which defines the impact of slope length and S-factor, which measures the effect of the slope angle. Therefore, LS-factor describes the effect of topography on soil erosion, showing areas susceptible to erosion processes.
