Dynamics of the Content of Mineral Forms of Nitrogen in the Water of Small Rivers in Khabarovsk During the Winter Period

This work is devoted to the study of the content of mineral forms of nitrogen in the water of small rivers in Khabarovsk and its surroundings, represented by the Bolshekhekhtsirsky Nature Reserve, during the winter low water of 2017-2021, which lasts from December to February. The dynamics of quantitative distribution of ammo-nium, nitrite, and nitrate nitrogen in relation to different groups of watercourses were considered. The correlation analysis enabled to reveal the probable reasons for such correlations of their content.
