Background. The scientific researching of the vegetation of Khanty-Mansi Autonomous Area – Yugra is insufficient at present, because investigations are carried out in actual natural protected territories. In doing so, Beloyarskiy district of KHMAA – Yugra is the most poorly-studied. The main task of our research is to ecologically and geobotanically assess the vegetation of the Lake Ay-Sortynglor environs.
Materials and methods. The research was executed on the basis of geobotanical descriptions according to the following scheme: classification using the Sorensen – Chekanovsky (Bray – Curtis) coefficient matrix with the Lance beta-flexible clustering strategy; biotopes phytoindication; non-metric multidimensional scaling; classification verification by General Discriminant Analysis algorithms; ordination in squared Mahalanobis distances and discriminant functions space; phytodiversity estimation. The computing was carried out in STATISTICA and PC-ORD software ackages.
Results. By methods of multivariate statistics on the structure of dominance, 9 associations of vegetation of the Lake Ay-Sortynglor area were identified. 12 species identified were informative in the classification of plant communities. The factors affecting the coenotic structure of vegetation were determined. There were established the regimes of the leading ecological regimes of biotopes of the distinguished associations, the series of ecological-coenotic substitution, and succession series of the studied plant associations and their biotopes.
Conclusions. The vegetation in the vicinity of Lake Ay-Sortynglor is characterized by a low level of species and coenotic diversity and is represented mainly by secondary birch-aspen and willow-shrub-pine associations. It has been established that the coenotic structure of the vegetation of the environs of Lake Ay-Sortynglor is determined by the acidity, moisture and granulometric composition of soils, as well as the presence and nature of the tree and (or) shrub canopy, which determines the light and temperature regime of biotopes.
