Abstract. The article considers the hydro-chemical regime of the Lake Zaysan during a number of years. Data on the change of the lake area and the content of the main and biogenic ions in the water of the lake during the period of 2008-2014 are given. The paper determines the category of waters according to the degree of mineralization and the class of hardness. The article analyzes the dynamics of the changes of the main hydro-chemical indexes of water from the side of Kurchum and Tarbagatay coasts, as well as of the lake on the whole. Changing the content of the main and biogenic ions depends on the fluctuations of the hydrological level of the lake.
Key words and phrases: качество природной воды, гидрохимический режим, содержание ионов, минерализация, жесткость, нитриты, нитраты, ионы аммония, фосфаты, quality of natural water, hydro-chemical regime, ions content, mineralization, hardness, nitrites, nitrates, ammonium ions, phosphates
