The main object of the article is to show indicator functions of small water bodies (streams, ponds) for 4 rural areas in agricultural landscapes (Belgorod region). In the course of the study the groups of anthropogenic objects with their special impacts are identified and ranked. The correlation between concentrations of chemical forms of biogenic elements (N, P) demonstrates the contribution of typical problems of agricultural landscapes in ecological situation (rural areas) as well as contribution of adjacent urban areas.
