The article considers the estimation of the levels of anthropogenic loads in the catchment areas of water bodies in the context of the anthropo-functional zones of the Alekseevsky District of the Belgorod Region. The results of this estimation are compared with the levels of water pollution by nitrogen compounds. It is shown that the hydroecological situation at the water bodies of the Alekseevsky District of the Belgorod Region is significantly differentiated. During the observation period, the maximum content of nitrogen compounds for all water bodies under study was noted in Alekseevka, in the river “Tikhaya Sosna” and in the spring (Chapaeva Street). The lowest values of the content of nitrogen compounds are recorded in the spring “Maznevskaya krinitsa” and in the river “Tikhaya Sosna” (Koltunovka village, 12 km below Alekseevka). The main factors contributing to the increase of nitrogen compounds concentration in the Alekseevsky water bodies are the influence of unorganized runoff from the territory of settlements and the close location of agricultural landscapes. Thus, an optimized scoring scale for anthropogenic load levels within different functional zones is proposed. Also, the data on the content of nitrites, nitrates and ammonium nitrogen in rivers, ponds, springs of Alekseevsky district of the Belgorod region are examined.
