The influence of anthropogenic factor on the landslide genesis is analyzed in this paper. Buildings, traffic, water supply and electro infrastructure are introduced in natural landscape as the result of human, living and economic activities in space. The conditions and processes which these objects can cause on the relation object-relief, and therefore initiate the occurrence of landslides, are the change of morphometric characteristics and the modifications of the water balance of slope. The zone with both qualitative and quantitative transformations of relief represents interactive zone in which the influence of man as a genetic factor or modifier of this colluvial process can be observed. .
