EVOLUTION AND MODERN STATE OF ECOSYSTEM OF THE UVILDU LAKE (SOUTH URALS)

The object of investigation: the ecosystem of the Uvildu lake, the bottom. The purpose of the work: the reconstruction of the main stages of evolution of the Uvildu lake on the base of the complex study of the bottom sediments and the evaluation of its up-to-date state with a view to justificate the measures on optimization of the nature use with the tendencies of development to be considered. The main evolution stages of the largest lake ecosystem of the Urals have been restored. The contradiction in the evaluation of the age of the most ancient lakes of the South Urals has been eliminated, and the time of its appearance the middle dryas has been determined. The most important peculiarities of the ecosystem modern state have been considered with the evolution direction taken into account. For the first time for the Urals, the most complete picture of evolution of the lake ecosystem has been presented, which can be used as the model (standard) of the rational nature utilization of the water ecosystem in the new qualified UralsAvailable from VNTIC / VNTIC - Scientific & Technical Information Centre of RussiaSIGLERURussian Federatio
