Abstract

The research is devoted to the study of plant component biodiversity as a criterion for forest ecosystems stability. The residual forest ecosystems of the towns of Kaluga and Obninsk were selected as the objects of the research. There are different approaches to the conservation of forests in the urban environment. The results of a-diversity indices both within one field season and by years were obtained. The level of reliability of differences in the samples was determined by Student’s /-test. Generally, in Kaluga, the a-diversity index is less in comparison to that in Obninsk. This indicates a higher species richness of the plant communities of Obninsk. The species richness of the Obninsk plant communities allows them to be more flexible to the effects of adverse factors, makes it possible to more fully use the ecosystem potential, compared to the forest ecosystems of Kaluga. Thus, taking into account the revealed facts, we can speak about greater stability of urban forest ecosystems in Obninsk.
