Purpose: to improve scientific approaches and evaluating methods of anthropogenic load at the local and sublocal levels of reclaimed agricultural landscapes.

Materials and methods. The study materials included scientific developments, methods for assessing and standardizing anthropogenic load to maintain ecosystem sustainability. The working hypothesis of the study is the suggestion, that it is necessary to consider both scale variables and parameters characterizing the intensity of production, when assessing the anthropogenic load of agricultural landscapes with regard to agricultural activity. In reclaimed agricultural landscapes, the priority component of the total anthropogenic load is irrigation.

Results. The methodology for determining the anthropogenic load on reclaimed agricultural landscapes has been improved by introducing a correction coefficient for the scale of the loading factor (activity), taking into account the intensity of the activity. A proposed definition of the coefficient is the ratio of the intensity of a certain type of anthropogenic load to the highest (maximum) intensity level that ensures the preservation of the ecological balance in a given ecosystem, squared. The problem of determining the correction coefficient when calculating water loads on reclaimed agricultural landscapes is solved. The problem is solved through the ratio of zonally provided (expected) irrigation rates, averaged for a crop rotation area, to the maximum value of water load that does not disrupt the stability of the ecosystem. When establishing the maximum value of water load, it is proposed to take into account the hydrogeological conditions of the territory, the technical characteristics of reclamation facilities, and the level of the irrigation technologies used.

Conclusions. New approaches to determining the magnitude of anthropogenic load on reclaimed agricultural landscapes are proposed. Maximum levels of water load that do not disrupt the stability of the ecosystem are determined for the dry steppe and semi-desert zones of the Lower Volga region.
