Abstract

Background. The data on forest-steppe landscape vegetation of water-glacial plains within Penza region are scarce. This publication aims to make public the data on the association of the main types of plant communities with the elements of the relief.
Materials and methods. Investigations were carried in the northwest region in Zemetchinsky district. The study of the floristic composition and structure of deciduous forests was carried at block and stationary studies on plots of 100 m2. The structural diversity of the communities was evaluated by the ratio of ecologiccoenotic groups of species in the composition of vegetation.
Results. The current vegetation cover of the Oka-Don plain in the Penza region is mainly represented by forests. The confinement of the allocated classification units to the types of terrain is noted.
Conclusions. At watersheds, landscapes of the suffusion depressions and lithogenic landscapes of intersubdominal spaces are occupied by forests (pine forests, birch forests, aspen) with domination in the grass of boreal species. On undulating
watersheds terrain, composed of low-power fluvioglacial deposits, communities with high participation of nemoral species are formed.

Key words

water-glacial plain, ecologic-coenotic groups, landscape, pine, birch, deciduous forests, aspen and alder forests
