Study of the Trophic Status and Ecological State of the Coastal Zones of the Natural Monuments of the Chelyabinsk Region (Russia) of the Turgoyak and Uvildy Lakes

Abstract

Human impact on the hydro-ecological state of water bodies affects every stage of water ecosystem formation. Such organisms as Phyto and zooplankton, which constitute the basis for trophic chains, are susceptible to the impact. The complex load has certain patterns of the spatial distribution of coastal geosystems with different stages of degression as a result of the direct recreational impact on natural hydrological monuments. Studying basic patterns of anthropogenic succession in lake agroecosystem, exploring Phyto and zooplankton communities, revealing natural and anthropogenic factors that determine their life cycles, and stating relationships between separate indices of a hydrological state of the lakes in South Ural and an anthropogenic load of geocomplexes near-by are of the utmost importance, especially for natural hydrological monuments. The purpose of this study is to carry out the zoning of the coastal landscape and recreational zones and the ecological state of the coastal territories of tectonic lakes at various spatial levels. For the study, complex water samples were taken in the summer of 2020 and 2021. To determine the trophic status, methods were used that included several criteria. They are the taxonomic structure and biomass of zooplankton, some hydroecological indices, and canonical correspondence analysis (CCA). It was determined that the natural basis for recreation is areas, mesogeosystems, and facies (on the example of tectonic lakes), with territorial formations where recreation facilities are formed playing the key role. The catchment areas of the studied lakes are more often represented by several landscapes and localities consisting of several dozen tracts.

Physicochemical characteristics of lakes along the southern Baltic Sea coast

“…A sharp deceleration in a watercourse’s inflow into a coastal water body accelerates the mineralization of organic matter and causes the deposition of allochthonous and autochthonous matter in the bottom sediments 9 . For this reason, waters flowing into the sea through coastal lakes may be less loaded with nutrients and organic matter than they would otherwise be 10 , 11 . Thus, coastal lakes act as sedimentation basins by reducing the pollutant flux from the catchment 12 – 14 .…”

“…В настоящее время видовое разнообразие фитопланктонного сообщества большинства высокоминерализованных водоемов России остается не изученным. В Уральском регионе многочисленные исследования водорослей в отдельных озерах имеются, но носят, как правило, не систематический характер и касаются в основном пресноводных водоемов [8,9,30]. Цель настоящего исследования -изучение эколого-географических характеристик фитопланктонных сообществ высокоминерализованных озер Челябинской области.…”
