Abstract
Features of reservoirs use make it necessary to collect, analyse and synthesise environmental information about the state of hydroecosystems with a purpose of their development forecast. Overgrowing processes are an important indicator of ecosystem. The following paper contains the results of the study of Chernovskoe reservoir flora and vegetation in different years. Floristic diversity is compared with other reservoirs and hydro botanic information about them has already been published in a number of the authors papers. The comparative analysis has shown that the overall composition of reservoirs flora is random, while there is some regularity in the environmental spectrum each of them is characterized by a small number of aquatic species and by the dominance of coastal plant species. The study of Chernovskoe reservoir vegetation has shown that the composition of dominants has changed over the past 40 years, from 1974 to 2015. There is a dominance of air water vegetation above the water one, but the borders of the water vegetation growth have widened. Chernovskoe reservoir is currently in dynamic equilibrium. The lifetime of aquatic ecosystem at this stage may be unlimited if there is an unstable hydro regime and impulsive character of water use. The reservoir water level lowering may lead to overgrowth and accelerate activation of waterlogging.

РЕЗУЛЬТАТЫ ГИДРОБОТАНИЧЕСКОГО МОНИТОРИНГА ЧЕРНОВСКОГО ВОДОХРАНИЛИЩА ЗА ПЕРИОД С 1974 ПО 2015 ГОДЫ В работе представлены результаты исследования флоры и растительности Черновского водохранилища в различные годы. Изучение растительности Черновского водохранилища показало, что за последние 40 лет, с 1974 по 2015 годы, она изменилась по составу доминантов, при этом сохранилось преобладание воздушно-
