Assessment of Lake Gusinoe Ecosystem Based on Macrophyte Analysis (Republic of Buryatia)

Lake Gusinoye is the largest lake in the Baikal natural territory after Lake. Baikal, around which the Gusnoozersky industrial complex is formed. In the macrophyte flora of the lake. 27 species from 21 families have been identified. The spatial structure of vegetation is determined by the morphometric characteristics of the lake's littoral zone. The northern and southern sectors of the lake are the most overgrown. Compared to previous years of research, an increase in the area of charophyte and moss thickets was revealed. The progressive overgrowing of the lake helps to maintain the processes of self-purification of the ecosystem, removes pollutants and nutrients from circulation and ensures the sustainable development of the ecosystem. The ability of the lake ecosystem to maintain the overall level of productivity due to restructuring of the structure is also evidenced by data on other communities of hydrobionts (zooplankton, zoobenthos and ichthyocenoses). The results of our studies of the chemical composition of macrophytes of Lake. Gusinoe showed, in comparison with the data of the 90s, the concentrations of chemical elements in macrophytes decreased. The recorded ecological state of the lake is determined by a complex of factors, both natural and natural (water level, temperature rise, littoral morphometry, chemical composition of water).
