The paper is aimed at the classification of anthropogenous networks in the landscape and evaluation of their influence on the landscape and its individual landscape components. Anthropogenous networks represent territorial expression of cumulative impact of stress factors. Similar as in the territorial system of ecological stability (TSES), in the territorial system of stress factors we can distinguish between nuclear components, line components, and large-area components: The territorial system of stress factors represents opposite system to the territorial system of ecological stability. Single stress factors represent barriers in relation to the TSES elements. The territorial collision of those opposite territorial systems causes different ecological problems in the landscape. The ecological problems can be divided into two basic groups: (1) Problems of the endangering of individual life forms (biodiversity) and (2) Problems of the endangering of conditions of the individual life forms.
