Abstract:
This paper presents the results of the research on macrophytes
of floodplain swamps of the coastal territories of the Aktastinka River and
wetlands of Aktasty village, located in Arshalinsky district, Akmola region of the
Republic of Kazakhstan. The inventory revealed the floristic composition of the
Aktastinka village locality and the coastal territory. Along with species diversity,
the main representatives of macrophytes of the bog flora were identified,
represented by 8 hydrophytes – Phragmites australis, Carex rostrata, Typha
angustifolia, Ranunculus repens L., Triglochin maritimum L., Stratiotes aloides L.,
Utricularia vulgaris L., Lemna minor L., etc. In the flora of the study area, four
types of plant communities were found, with the dominance of representatives
of the following families: Poaceae, Typhaceae, Cyperaceae, Ranunculaceae,
Amaryllidaceae, Butomaceae, and Lentibulariaceae spanning several kilometres.
Comparative analysis of macrophyte floras at four different sites illustrated
similarity between phytocenoses. The plant flora of the study area includes
105 species belonging to 65 general and 38 families. Dicotyledonous plants are
represented by 78 species, monocotyledones plants by 27 species. The ratio of
dicotyledons to annuals was 1:2.9. On average, each genus is represented by 2.3
species, species saturation of families is characterised by the average index, and
is 9.5.
