Data confidence 70 medium
How this score is calculated

It is built from checkable properties of the record itself: whether the article has a DOI, how many independent sources confirmed its data, whether the required fields are filled in, and how recent the latest confirmation is. Disagreement between sources and a missing identifier lower it. A value of 80 or above means the record was published without further checking; 60 to 79 means it is published at reduced confidence, with a manual check advisable. A record verified by an editor by hand is never pushed below 90 by a recalculation. This scores our data about the article, not the article itself.

Abstract

The vegetation of 5 lakes and 40 springs of Western Kazakhstan was considered. The relationship between the degree of mineralization and the composition of vegetation was revealed. The anthropogenic factor influences the vegetation of lakes and springs by increasing the number of ruderal and halophytic plants. With a decrease in the water level in lakes, processes of active salinization of the water area and the coastal part are observed, an indicator of which is vegetation. In the territories adjacent to the springs, the dominant role of mesotrophs and megatrophs in the structure of the flora of the springs was noted, which indicates the predominance of soils and soils with sufficient and excessive content of nutrients in the studied area. The flora of the region’s springs has a low degree of similarity. Cluster analysis of the flora of spring tracts confirmed the heterogeneity of quantitative species composition.
